Fool me twice

The Cons started talking about a "new role" in Afghanistan two years ago but nobody was really listening. Then last fall during the election campaign, Harper suddenly announced that Canadian troops would leave Afghanistan by 2011.
Canadians believed him.
Fool me once, shame on you. Fool me twice, shame on me -- now MacKay is saying we will stay after all and Warren Kinsella helpfully explains the apparent contradiction:

They've been lying. That's the bottom line. And if they get their lusted-after majority, Canada will be there long after 2011.

Quel suprise!
