With what Donald Trump says he will do when he gets in as president, I sure hope that he takes the protection of his country seriously but not too seriously or he will alienate more countries than Obama already has done.
In addition, I would say that the outcome of an overly hostile stance towards other countries would not be too good for America. That's because you have to take into consideration how outgoing president Obama has diminished the strength of the military to the point that the USA could no longer sustain a dragged out war.

I know one thing for sure - we don't have a Prime Minister in Canada that will be able to stand up to Trump.
