Not really important that Trump lied to Trudeau, in fact, world leaders do it all the time. Although this may be a first that a politician lied to another one and then went to his supporter, in front of cameras, and bragged that he lied, that he had no idea as to the state of the Canada/USA trade balance, and in the end didn't really give a sh$t! That's new! I would guess that any world leader now will wonder what's the point of having a head-to-head with Trump. He's likely to lie about everything and it has no impact on policy. It's not so much that Trump should "go home" rather he should "stay home" because it is evident now that what comes out of his "pie hole" is inconsequential for other nations...not only does he make stuff up, he doesn't care what it means -- why then engage the man!
