September 11, 2001 was a day in history that will never be forgotten. A total of 2,977 people lost their lives that day. 19 militants from the terrorist group al-Qaeda hijacked four planes. Two of these planes hit the Twin Towers in New York, one of the planes hit the Pentagon outside of Washington, D.C., and the last one crash in a field in Pennsylvania.
After the attack, the U.S. had sympathy from almost the entire Muslim world, but as soon as the U.S. retaliated with violence, all sympathy was lost. This "fanatical Islamism" soon gained support of most of the Muslim world. Wars broke out in Iraq and Afghanistan with the U.S., costing tens of thousands of lives and causing mass destruction. The financial costs of the wars were mainly based on borrowing which has destabilized the world economy.
