“We’ve benefited since the Second World War from a whole number of co-operative arrangements with the United States on defence where the U.S. carries a disproportionate share financially.”

The US activity in the Middle East and surrounding area deserved exactly zero support. The US started by financing the takeover of land in Palestine. The Arabs-Muslims retaliated, hitting US embassies in Africa. Then a US Naval vessel. The US attacked a factory in Khartoum while continuing support of takeover of land in Palestine. Then 9-11, just another battle in the war. For shame Canada joined the US attack on an innocent country, its government taken over by the US. 

It is good to hear that the US may withdraw from NATO. The US lead NATO into obscene activities, such as Afghanistan. Canada could and should withdraw from NATO and disconnect militarily from the US. There is no common enemy.
