Iran talks in Baghdad: Western naivet
It?s hard to overestimate the degree of naivet? on the part of the West as it heads toward another round of nuclear talks with Iran in Baghdad on Wednesday.
Clearly, Iran is stalling for time to develop a nuclear weapon. One example: In talks last month in Istanbul, Tehran seems to have convinced international negotiators of the sincerity and weight of a fatwa, or religious edict, by the Supreme Leader Ayatollah Ali Khamenei that a nuclear bomb is haram ? forbidden ? in Islam.
Last week, for instance, former French Prime Minister Michel Rocard said the fatwa will help promote confidence about Iran?s nuclear activities.
OPINION:?3 reasons not to attack Iran
The ayatollah is not beholden to keep his word, but that doesn?t seem to be of much concern. At the Istanbul talks, the West agreed for the first time to Iran?s demand that it may enrich uranium, with restrictions ? despite UN resolutions to the contrary.
The Islamic regime has continuously believed that the more its nuclear program is expanded and progress is achieved, the less likely the West will demand a halt to the program ? and if Iranian leaders remain steadfast in the face of all threats, the more likely the West will eventually accept a nuclear Iran.
Recent chronology bears this out.
When President Obama took office in 2009, Iran was under several UN sanctions conditioned on its suspension of all uranium enrichment-related and reprocessing activities. At the time, Iran had 1,200 kilos of low-enriched uranium at its Natanz facility.
Mr. Obama chose to engage the Islamic regime, believing that an extended hand would yield better results than threats. He reasoned that a new US approach would be welcomed by Tehran because it was a complete change from the Bush administration.
However, the radicals ruling Iran saw this extended hand as weakness. They engaged the Obama administration while enriching uranium beyond the benign 3.5 percent level, as it had been limited to for many years, to the 20 percent level. While that is not a high enough enrichment level for a nuclear weapon, it is high enough to get to bomb-grade very quickly ? in a matter of weeks if Tehran decides to do so.
Early in 2010, Obama, realizing his defeat in the negotiation phase, moved to a sanctions phase. But instead of the crippling sanctions he had promised, he started step-by-step sanctions that Iran?s clerics saw as further proof of America?s inability to stop Iran, which emboldened them to speed up their program.
OPINION:?5 reasons US must avoid war with Iran
Today Iran, under further sanctions by the United Nations, United States, and European Union, has over 5.5 tons of enriched uranium ? enough to eventually make six nuclear bombs. It continues to enrich uranium with more than 9,000 centrifuges at Natanz, both at the 3.5 and 20 percent levels, and at the previously secret site, the Fordow facility, deep in a mountain near the city of Qom, to the 20 percent level.
All the while Iran is expanding the number of centrifuges at both sites, with a possibility that there are more sites unknown to the West or the International Atomic Energy Agency.
This takes us to the current set of negotiations. In Instanbul, the West handed the Islamic regime a historic win. For the first time in the negotiations over Iran?s nuclear program, the West offered Iran full acceptance of its nuclear enrichment process if Iran stopped the 20-percent enrichment.
In other words, the West has caved to Iranian demands of accepting its domestic nuclear enrichment.
Most interesting is an Iranian analysis of Khamenei?s fatwa: ?If the Obama administration realizes the importance of the place of the supreme leader in Iran and understands the fatwa, then most of their problem [with Iran?s nuclear issue] will be solved.?
The analysis ominously stated: ?There will be no other guarantee beyond the fatwa to the West? ? meaning that the West will only get the word of a leader whose regime has been based on lies and deceit, a leader who has ordered the slaughter of thousands of Iranians ? and also Americans ? in Iraq and Afghanistan, and a leader who constantly threatens the existence of Israel and the ?defeat? of America.
ANOTHER VIEW: Iran nuclear talks: To keep global support, US must seize diplomatic opportunities
Khamenei is not a grand ayatollah, or a marja, and therefore cannot issue a fatwa. Many in Iran?s Islamic leadership know this. He was elevated to ayatollah status overnight to replace Ruhollah Khomeini when he died in 1989. Even if a marja issues a fatwa, he can overturn it if it benefits Islam. So Khamenei?s fatwa can be tossed out at the right time.
Interestingly, the regime?s interpretation of the Quran is to deceive its enemy, i.e. the West, until such time as the regime is strong enough to confront it.
Is Obama so naive as to hang on to a fake fatwa in return for accepting a nuclear Iran?
His secretary of state, Hillary Rodham Clinton, says she has discussed the fatwa with Turkey?s prime minister, experts, and religious scholars. ?If it is indeed a statement of principle, of values, then it is a starting point for being operationalized, which means that it serves as the entryway into a negotiation as to how you demonstrate that it is indeed a sincere, authentic statement of conviction,? she said last month.
According to media reports, the US is expected to push Iran to close its Fordow facility and send its stockpile of medium-enriched uranium out of the country.
Iran has ruled out the closure of Fordow, even announcing that it will increase the number of centrifuges at that facility. And so far, its strategy of expanding its nuclear program while wearing down the West has already proved successful.?
OPINION:?Five reasons to attack Iran
It is clear that after a decade of negotiations and sanctions, the leaders of the Islamic regime will not accept a full halt to their nuclear program. But given that Iran now has the know-how to make a bomb, that is the only outcome that should be acceptable to the West.

Fencing is a sport of European ancestry with origins in weapons of war and dueling. The latter could be thought of as a combination of war and sport, because the duelists did not fight to the death but only to save their honor. A cut across the cheek was a common trademark of dueling with the sword as late as the 20th century. Today, the sport involves blunted weapons and a linear fencing area in which two people attempt to score touch?s (contacts of the weapon to the body) on each other (Fig. 23.1). It is a sport of intense physical and mental activity, and the two opponents are within 6 feet (2 m) of each other most of the time.
FIGURE 23.1. Fencing is a sport in which two people attempt to score touch?s on one another by using blunted weapons on linear fencing area.
The U.S. competitions and rules are governed by the United States Fencing Association (USFA); fencing's National Governing Body, which is recognized by the U.S. Olympic Committee; and the International Fencing Federation, or Federation Internationale d'Escrime (FIE). The USFA was founded as the Amateur Fencers League of America in 1891. The technical rules established by the FIE are, in most cases, the same rules adopted by the USFA and therefore are the rules used to govern fencing in the United States. These rules address such issues as equipment and technique, safety, injury timeouts, and drug testing.
The USFA also is the official body that chooses the national teams to represent the United States in international competitions, including world championships. Point-awarding competitions (North American circuit and national junior and senior championships) are offered for the purpose of selecting these teams. International competitions include world cups, world championships (junior and senior), the Pan American Games, the World University Games, and the Olympic Games.
Three weapons are used in fencing: the ?p?e, the foil, and the sabre (Fig. 23.2). Each weapon has its own design and rules of play. All three weapons are fenced by men in international contests, but only the foil and ?p?e are fenced by women in the Olympic Games, but all three weapons have World Cup events. National, sectional, and divisional USFA-sanctioned competitions are offered in all three weapons to both men and women. There are children's events (under 14 years and under 17 years), junior events (under 20 years), open events, and senior events (40 years and older). University and high school leagues also exist and are governed by the appropriate athletic governing bodies. In the schools, female competitions have been limited to the foil. There have been, however, instances when women have fenced on the male ?p?e and sabre teams, because there were no women's teams with these weapons.
FIGURE 23.2. The three weapons used in fencing are the ?p?e (top), the sabre (middle), and the foil (bottom).
Another form of fencing competition is designed for athletes with physical impairments. National and international wheelchair fencing require that the participants fence from a sitting position. These competitions are governed by the relevant national and international disabled sports organizations.
Fencing is offered throughout the United States in many major cities and in some remote towns through recreation programs, private clubs, health and sport clubs, and fencing clubs. The fencing club is known as a fencing salle, and the fencing coach, if a graduate of a fencing school, is known as a fencing master (maistro).
Fencing equipment is usually provided by the schools and by the facilities offering novice classes. After the class stage and as the fencers begin to compete and become members of a club, students usually must purchase their own equipment. The mask, weapon, glove, and uniform (exclusive of the shoes) cost approximately $200. If the equipment is certified for international competition, the price is approximately $500, which includes three weapons. All the equipment sold in the United States must meet the fencing standards approved by the FIE for safe fencing. All pertinent equipment must be properly inspected by the technical committee before competition. Most teams and competition sites have equipment specialists (armorers) as part of their entourage to ensure that the equipment meets FIE safety standards (Fig. 23.3). Because scoring is based on electrical contact, the armorer also ensures that the equipment has been assembled in such a way as to avoid a malfunction or misrepresentation of the electrical scoring system.
FIGURE 23.3. The armorer is the individual who officially inspects fencing equipment to ensure the athletes' safety.
Fencing equipment and wear has been designed with the athlete's safety in mind. For all three weapons, the protective jacket must overlap the knickers (or uniform of Kevlar-type material), a plastron is mandatory, and women must wear breast protectors. The glove must cover at least one half of the forearm so that the opponent's weapon cannot enter the sleeve. All masks must be checked by an instrument with a spring-loaded point before competition to ensure that the mask cannot be penetrated by the opponent's blade. This instrument must be able to withstand a 12-kg force (1).
To prevent injury, there are rules governing the methods by which one fences. It is strictly forbidden for a fencer to perform any abnormal motion, such as severe hits or opponent collision, that may be construed as discourteous and dangerous (1).
RULES OF PLAY
Fencing has several courtesies, including saluting of the opponent and the director (official) at the beginning of each match and shaking hands with the opponent afterward. The mask, weapon, and clothing of both fencers are evaluated by the director before the start of the bout. The fencers assume the ready position (en garde). The referee says ?Fence,? and fencers fence until the referee says ?Halt.? When there have been five touch?s scored by one fencer, the bout is ended and that fencer is declared the winner. During some competitions and at later stages of a large competition, fencers must win with a margin of two touch?s in two of three bouts, to a maximum score of 6 in each bout.
The area of fencing is a linear strip (piste) approximately 5 feet (1.5 m) wide and 47 feet (14 m) long (Fig. 23.4). The fencers exchange a series of offensive attacks and defensive actions consisting of advances, retreats, lunges, and fl?ches in which the feet are usually at right angles to each other and the legs are in continual semiflexion or vigorously extending (Fig. 23.5). Defense involves retreats and arm flexion movements. Attack arm actions are primarily elbow and wrist extension and lateral or circular movements of the hand and forearm.
FIGURE 23.4. The piste is the linear strip on which fencers compete.
FIGURE 23.5. A series of attacks and defensive actions produces vigorous extremity movements, and mechanical stresses are common in the sport of fencing.
Because of the rules and target area for valid touch?s, the actions of the arm when using the foil are more restrictive than with the other two weapons. Only the torso is a legal target. Lunges are prominent in the foil strategy. The rule of right-of-way results in a rather definite pattern of attack?defend?attack?defend before a hit (contact) is made. Right-of-way refers to the need of a fencer to initiate an attack before the opposing fencer does.
In the sabre competition, the target is expanded to include the head and arms. In addition, the cutting edge of the blade may be used to score a touch?. For these reasons, there is a greater variety of arm actions than with the foil. The fl?che is used more extensively than the lunge. The right-of-way rule also applies to the sabre.
The total body is the legal target in the ?p?e, and no right-of-way rule exists. Both fencers can score a touch? simultaneously as long as it is done within 1/25 second. As with the foil, only the point of the ?p?e can be used to score a legal touch?. Lunges are used, but the fencers rely frequently on their quickness or reaction time, and some do not often lunge.
EPIDEMIOLOGY
Acute Injuries
Because of the nature of the sport, fencing produces a wide diversity of acute injuries. A 2-year study was performed by the USFA's medical commission to investigate the actual frequency and distribution of such injuries. This study was conducted from 1988 to 1990 at all North American Circuit (NAC) events and two national championships (each weapon has three NAC events and nationals). During this time, 586 injuries were reported by the fencers to official medical personnel, in most cases a certified athletic trainer. Only 323 of the 586 reported injuries were acute injuries requiring medical attention. (Non acute injuries included sinusitis and diarrhea.) All acute injuries requiring medical treatment were documented on the Fencing Treatment Form IQ (Appendix A). In addition, for any significant injury that required stabilization, transport, and possible future medical treatment, the Injury Initial Evaluation Form was also completed (Appendix B); this form was reviewed by the physician onsite or on call whenever possible.
Relationship Between Acute Injuries and Weapons
To determine whether the differences in injury ratio (type of injury and body part injured) for each weapon (men's foil, women's foil, men's ?p?e, women's ?p?e, men's sabre, and women's sabre) were the result of chance alone or whether the results were caused by significant differences between groups, a statistical analysis using a chi-square and Cramer's V value was performed.
When weapons were compared with body parts injured, a statistical significance was found among the variables (p = .0177); however, the Cramer's V value indicated that this relationship was not strong (V = .32618). It was concluded that the body part injured may depend on the type of weapon. When comparing the weapon with the type of injury, researchers found the p value to be .0838 and Cramer'sV value to be .18098, indicating no statistically significant relationship between these two variables.
Distribution and Types
Of all injuries reported during the study almost 33% were sprains (more than 50% of which occurred during men's ?p?e events). Strains were the second most common injuries (23.8%), followed by heat-related disorders (17.9%), contusions (6.2%), fractures and complete tendon ruptures (1.2%), and other miscellaneous systemic disorders (0.3%) (Table 23.1, Fig. 23.6).
TABLE 23.1. TYPES OF ACUTE FENCING INJURIES (%)
FIGURE 23.6. Percentage of acute injuries in men's and women's fencing. Numbers are based on men's and women's fencing combined. (Graphs courtesy of D. Grygo.)
Comparing all six weapons, men's ?p?e accounted for the most injuries, 45.8%. Men's sabre represented 20.7% of all injuries, and men's foil, 10.5%. This may be partially attributed to the fact that the ?p?e has a much larger target area than the sabre or foil. Furthermore, the ?p?e is of greater stiffness and weight compared with the other weapons.
Of the three women's events, women's foil represented 15.2% of the total injuries, compared with 6.8% for ?p?e and 0.9% for sabre. This may be accounted for in part because more women compete in women's foil than in women's ?p?e or sabre.
Location
In terms of body part, a significantly higher number of injuries occurred at the ankle (15.8%) compared with the other 23 sites observed (Table 23.2, Fig. 23.7).
TABLE 23.2. LOCATION OF FENCING INJURIES (%)
FIGURE 23.7. Percentage of acute injuries by body part in men's and women's fencing. Numbers are based on men's and women's fencing combined. (Graphs courtesy of D. Grygo.)
Pages: 1 ? 2 ? 3
The total body (systemic) was the location for the second most frequently treated acute disorders (usually heat related) at 10.5%, followed by the hand (8.4%) and the knee (8%).
Types of Acute Injuries
Because of the planted, flexed, and externally rotated valgus-stressed position of the trail leg, acute injuries such as medial collateral ligament sprains, medial meniscal tears, lateral subluxating patella, groin strains, ruptured Achilles tendons, and eversion ankle sprains have been observed. Quadriceps strains, blisters, and nail contusions have been noted in the front leg. Because the trunk is a target area for all three weapons (in addition to the upper extremities for the sabre and ?p?e), more contusions and lacerations are seen in this area.
Gender Differences
Over one academic year, men's and women's collegiate fencing injuries were monitored and compared. When adjusted for exposure time, no significant gender differences were found. Approximately 0.10 injuries per 100 person-hours were noted in men's fencing, compared with 0.18 in women's fencing. There were 0.43 disability days per 100 person-hours associated with these injuries for men, compared with 0.21 days for women. Overall, 28% of men participating in fencing were injured, compared with 50% of women (2).
