This is in 2008 .. Obama was readying US Troops in Canada

On February 14th, Canada and the US signed an agreement which allows for the deployment of US troops inside Canada.

There was no official announcement nor was there a formal decision at the governmental level.

In fact the agreement was barely mentioned by the Canadian media.

The agreement, which raises far reaching issues of national sovereignty, was not between the two governments. It was signed by military commanding officers.
