thousands of other documents. Analysts have identified a number of characteristics of the United States’ agricultural system that make it very vulnerable to agroterrorism. Given that agriculture generally demands large expanses of land, farms are geographically dispersed in environments that are difficult to secure. Also, livestock are usually concentrated in confined locations, which allows diseases to infect more animals quickly. Although many experts believe the United States is susceptible to agroterrorism, they have never suffered from a large scale agroterrorism related attack. Many political scientists have identified the 1984 salmonella attack in The Dalles, Oregon as a small-scale example of an agroterrorism attack in the United States. A religious cult intentionally contaminated ten restaurant salad bars with salmonella in an attempt to influence a local election, sickening more than 750 people. Even though the United States has not experienced a large-scale agroterrorism attack to date, similar to its anti-bioterrorism initiatives, the United States government has passed several pieces of legislation and started initiatives over the past few decades to better secure its agricultural system and prepare for potential attacks. Nuclear weapons Concerns have also been raised regarding attacks involving nuclear weapons. It is considered plausible that terrorists could acquire a nuclear weapon. In 2011, the British news agency, the Telegraph, received leaked documents regarding the Guantanamo Bay interrogations of Khalid Sheikh Mohammed. The documents cited Khalid saying that, if Osama Bin Laden is captured or killed by the Coalition of the Willing, an Al-Qaeda sleeper cell will detonate a "weapon of mass destruction" in a "secret location" in Europe, and promised it would be "a nuclear hellstorm". While no terrorist group has ever successfully acquired and used a nuclear weapon, many political scientists and prominent government officials consider nuclear terrorism to be one of the single greatest threats in global security. There is strong evidence that terrorist groups like Al-Qaeda are actively seeking to acquire nuclear weapons, and the plutonium or highly enriched uranium (HEU) needed to produce them. Another serious concern is that weaknesses in many states’ nuclear security apparatuses have left them susceptible to theft or loss of HEU or plutonium. According to the International Atomic Energy Agency's (IAEA) Illicit Trafficking Database (ITDB), there have been 18 incidents of theft or loss of HEU and plutonium reported in ITDB's participating states. Given these serious concerns, the United States, its allies, and international organizations like the United Nations have
