"It is Mr. Trudeau’s problem, arguably one of his own making."

Well, let's argue that.  

Yes, no question: Trudeau's foot-in-tweet come-one-come-all message really did it.  But the REAL problem?  Social media.  Well, no stopping that.  Next problem: the American President's deportation rhetoric. Well, no stopping that, either, even if Mr. Kelly is Chief of Staff.  It's hot air, really (US couldn't afford the costs to deport everyone it doesn't--suddenly--approve of.). But that doesn't matter, once fear sets in.  

Hot air from the Whitehouse: We're clamping down; we don't want you and you're gonna go. Hot air from Ottawa: y'all come!

And a long undefended border.  

The perfect storm.  

Haitians may only be the START of this thing...
