NATO was useful while the USSR existed. But when NATO was used to attack Afghanistan it was disgraceful. The US had attacked Arabs in Palestine. When Arabs responded with 9 11, the US called for help  - with a war that it started! NATO countries went along by agreeing to join the US, then for the most part gave token responses. In any event NATO became an offensive organization. 

Canada should be more careful in making alliances. NATO cost 156 lives and billons of dollars

Further by keeping troop in Muslim countries we can expect a Muslim response. What are our troops doing there.
