The US said its troops were advisors. They quickly became fighters. We evidently have done the same thing. Our troops are killing Muslims.  We should expect retaliation. Note that every western country which has been attacked previously attacked Muslims.

My proposal to withdraw troops is based on the fact that they are not defending Canada. 

"It means there are no repercussions for whatever you choose to do"

That is exactly what NATO and the US agreed on. The US attacked Palestine and when the Arabs responded with 9/11, the US called for NATO to respond. 

There were no repercussions for the US attacking Palestine. NONE. And as would be expected the US continued its carnage. Iraq for starters. 

Bringing the troops home is in keeping with the fact that Canada had not been attacked. We, not the Muslims, started it by joining the US in attacking Afghanistan.  

My apologies for population figures. I punched in again and got 2.1, 1.8 and 1.6 billion Muslims in the world.
