Maybe pull Canadian troops out of Kandahar and present the US with the need to find another battle group on short notice to replace the Canadian one. Good luck on getting NAYO to kick in troops to that hot theatre,
Note that the Canada bashers did not seem to recognize in this article the fact that the US only knows about these people because of the close co-operation between the two countries' enforcement and intel agencies.
Yet The suggested response by at least one Freeper on this thread is to reward this co-operation by bombing Canada.
