Canada

For anyone wondering why Canada is not eager for military spending, it's because very little goes into our own Canadian economy. We don't have much military industry (and we're not big enough to ever get much) so most of the money spent goes to buying foreign equipment. It's like a permanent export of cash. Planes, rifles, even ship building - we can build the ship, but then we buy all the electronics and weapons systems from someone else.

And not to sound too crass, but for what reason? No one is going to invade Canada because of geography. The US? We have no chance anyway. We could leave NATO and pretty much disband our military entirely. The only reason we're in NATO and have a military is to help others. Again, at extraordinary expense because we don't have our own domestic military industry.
