Last time I looked NAFTA was still in effect. So why are we acting relieved/grateful that the US has not applied "Buy America" standards on who makes the pipeline? Under the "national treatment " clauses of NAFTA each partner has to treat the other as if they were a national of their own country... no discrimination. We've already won this issue over meat labelling. If Trump wants out he needs to give 6 months notice or a "tweaking" has to begin but he cant just decide that parts of it don't apply to him. Why are we so wussy?! If he gets away with this he'll know he can get away with another thing and before you know it NAFTA wont have to be tweaked it'll just apply to Canada and Mexico and the US will do whatever it wants; the classic power play. Softwood lumber in the balance.
