9/11 was one battle in a war that started with the US funding and arming the takeover of land in Palestine. The Arabs retaliated with attacks on embassies in Africa and a US naval ship. The US continued funding the takeover of Palestinian land and attacked a factory in Khartoum and caves in Afghanistan. Then 9/11 which was a brilliant strategic move to try and knock out  the heart of the US, its financial district and military headquarters. That failed and the US showed how quickly it could recover. Then the US and NATO went in to Afghanistan. 

Imagine an agreement, NATO, where the US attacked Arabs and when the Arabs responded the US claimed it had been attacked (it had been retaliated against) and all NATO countries agreed in legal terms and then most gave token support. 

A NATO country attacks an Arab country and when the Arabs respond all NATO is involved!! 

Canada like all NATO countries did not stand up to the US. 159 Canadian troops died in an immoral war.
