The Liberals are mostly doing the right thing in regard to relations with the  US, and the Trump White House.

Even so, I find the whole Trudeau-Trump relationship very funny.  I recall the Liberals:

Many who attended the American Ambassador's election party
Kathleen Wynne going to the American Consulate in Toronto for their party, 
(they weren't attending to "celebrate American democracy in action" despite their saying otherwise)

Obama lending his advisors to the 2015 Liberal campaign (Should have kept them fresh for the US election, eh, Barack?).

Obama's press allies and their fawning media coverage over Trudeau.
The likely long pre-planned Joe Biden-Trudeau dinner after the election.

And now, at least for the time being, the Liberals are forced to make nice to Trump.

Oh well, I'm just petty I suppose.
