The west had attacked Arabs/Muslims before the west was attacked. First, the US financed the take over of land in Palestine and armed Israel. Arabs responded with attacks on embassies in Africa and a US Navy vessel while the US continued to finance Israel. The US attacked a plant in Khartoum and caves in Afghanistan. Then 9/11. The west attacked Afghanistan. I was certainly appalled that the world's super power had attacked a defenseless country. I assume others, especially Muslims would feel the same way. Then the US and Britain and others attacked Iraq. Muslims attacked Britain and Italy and Spain. Then Germany and this latest in Britain. They are all battles in a war. Attack and retaliation. 

Common sense would say that if the west stopped interfering in Muslim countries, attacks on Western countries may abate. Certainly, given the record, retaliation by Muslims is guaranteed if we continue. 

Why have troops in the Middle East area? Canada has NO interests there.
