Comment: There should be no surprise, just as there should have been no surprise with 9/11, if US and Air Canada planes are attacked. The US has been killing  people in the Middle East and environs since WW2, Canada since 2001. In fact given the record of attacks on countries which have killed in that area, it would be surprising if there were no attacks. The most appropriate attack was on Parliament Hill where the decision was made for Canada to attack in Afghanistan.
