Caen10 In a wing of the museum titled "Worlds for Peace", there's a remembrance for the attack of "9/11". It's the only place outside the US that has remains of the World Trade Center. Four fragments of beams of the World Trade Center Donation: New York City, 2002 The 11 September 2001 will remain etched in everyone's memories as a striking fact of 21st century history. This event has provoked a genuine traumatism that has modified American foreign policy in the long term, now focused on "total war against terrorism". Ever since, attacks in Iraq, Egypt, Turkey, Indonesia and Jordan, as well as Madrid and London, have confirmed the threats that are weighing upon democracies who are unarmed against this new type of war. On this day, two airliners were hijacked by a group of terrorists from the Al-Qaeda network and flown into the towers of the World Trade Center in New York, a symbol of American economic power. A short while afterwards, another hijacked plane crashed into the Pentagon, the center of military power. A third attack was due to strike the White House or the Capitol, both symbols of political power, but the plane crashed twenty minutes flight away from Washington. For the first time in history, the United States was attacked on home territory. Moreover, the number of victims was unprecedented in an attack: more than 2,900 of 90 different nationalities.
