Nobody in Canada or Europe actually wants to lead.
Obama gave Europe a chance to stand up and lead. He gave Europe a choice and America would follow.
But nooooooo, you know what's the fist thing they did? Their leaders started going on TV whining and bitching that they wouldn't do anything until the Americans made the first move (this was back then regarding the financial crisis).
For the first time, during the financial crisis, Europe had the decision to lead the world, but then they showed their true colors that Europeans do not have the guts or the will to lead the free world. And Canada is worse than Europeans when it comes to global politics. Canada is the proverbial back-seat passenger.
Next time you want to question America's position as the leader of the free world, ask yourself if you'd be willing to take it up instead. If your answer is no, then shut the fuck up.
