Right now, anything supportive of the USA military is a definite political no-no up this way. Prime Minister Martin is on past record as being supportive of the "missile shield", but he knows he'd be rapidly turfed if he openly supported it at this point. Blame Bush.

On the other hand (as others in this thread have noticed), there's nothing we (Canada) really would have to do anyway, beyond allowing N.O.R.A.D. data to be used to trigger missile launches. And my New Brunswick pseudo-kin (ex-Premier Frankie McKenna, as oppsed to current Premier cousin Bernie Lord) has already pointed that out, which kinda forced the recent reverse announcement.

Cheers
