CNN recently published an article entitled Study: Threat of Muslim-American terrorism in U.S. exaggerated; according to a study released by Duke University and the University of North Carolina at Chapel Hill, "the terrorist threat posed by radicalized Muslim-Americans has been exaggerated."
On the FBI's official website, there exists a chronological list of all terrorist attacks committed on U.S. soil from the year 1980 all the way to 2005. According to this data, there were more Jewish acts of terrorism within the United States than Islamic (7% vs 6%).
Over in Europe - Europol publishes an annual report entitled EU Terrorism Situation and Trend Report. It states from 2006 to 2010 there has only been .04% of Terrorist attacks by Islamic Extremists and in the 2011 report it states in 2010 there were only 3 attacks in Europe compared to the total of 249 attacks by all other groups.
There is no other single word more synonymous with Islam and Muslims today than the word terrorism. We all witnessed the USA declaring war on terrorism in 1981 and again in 2001, unaware at the time of the terrible fraud behind those accused crimes.
Noam Chomsky has argued that the major sources of international terrorism are the world's major powers, led by the United States.
He uses a definition of terrorism from a US army manual, which defines it as "the calculated use of violence or threat of violence to attain goals that are political, religious, or ideological in nature. This is done through intimidation, coercion, or instilling fear" US Army Operational Concept for Terrorism Counteraction (TRADOC Pamphlet No. 525-37), 1984.
