Why Are Terrorists Attacking Canada?

Doesn't make any sense to me. Why Canada?

The RCMP has quietly broken up at least a dozen terrorist groups in the past two years, according to documents obtained by The Globe and Mail.

"We have completed 12 disruptions of national-level terrorist groups across the country," the Mounties say in briefing notes prepared for Public Safety Minister Stockwell Day.

Disruptive tactics -- sometimes as simple as letting targets know they are under close surveillance -- are used to prevent a terrorist attack when the police do not have enough evidence to lay criminal charges, the RCMP and the Canadian Security Intelligence Service say.

A more troubling thought is, if the RCMP has broken up a dozen terrorist groups and foiled these attacks, what has been going on in the USA?
