Canada would be dumb to go forward, everyone knows the US has kill switches in their gear and now might hostilely engage canada, perhaps to steal territory, and otherwise has talked of invading other nato countries like in Greenland.

In which case the US could brick all of the gear they sold them. It's already bad enough, Canada has to buy from EADS or whomever builds their air forces, I would not trust the UK either at this point, they are properfucked by their own neoliberal type politicians in labour, that have done more damage than the tories the past couple of years..
