The most difficult Ter­ror­ism riddles

A study reveals that U.S. military forces were directly responsible for about 10 to 15 million deaths during the Korean and Vietnam Wars and the two Iraq Wars. The American public probably is not aware of these numbers and knows even less about the proxy wars for which the United States is also responsible. In the later wars, there were between nine and 14 million deaths in Afghanistan, Angola, Democratic Republic of the Congo, East Timor, Guatemala, Indonesia, Pakistan and Sudan.

Osama bin Laden, the founder and first leader of the Islamist group Al-Qaeda, was killed in Pakistan on May 2, 2011, by United States Navy SEALs of the U.S. Naval Special Warfare Development Group. The operation, code-named Operation Neptune Spear ended a nearly 10-year search for bin Laden, following his role in the September 11 attacks on the United States.

The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda on the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage.
