dude you realize canada's population is like a tenth of the americas right? if we were to have 1.5 million troops that would mean every 1 in 10 citizens or so would be serving. I dont think thats even possible unless your like isreal where everyone has to serve for a set time. and for the defense budget? i dont think we generate 400 billion in tax revenue period.
Its like comparing a mac truck to a beetle, you just cant do it. The countries populations are just too extreme for a straight comparison
