Canada has more than pulled its weight internationally and at US behest in Bosnia, in Afghanistan, "Ukraine" and in bombing Libya into chaos.  And that's just recent violence.
The US only pays attention to itself and frankly seems surprised when the UK, it's always ally in any rotten war, pops up and offers to kill for the favourable nod of the US.

And your whole argument is a reprehensible, "let's use the blood of our soldiers to grease the wheels of industry".  

But that's the kind of argument the Reform/Cons make without a shadow of shame although they are drenched in it.
