NAFTA will bite Odumbo on the backside with this one. he will be unable to block it through legal challenges. This treaty has provisions that prevent the trade agreement. Odumbo believes because his political agenda is not in correlation with NAFTA, he can drag his feet. The problem is when he had Congress pass TPP, ne simply forgot that he gave board powers to other nations to utilize powers given in NAFTA to be utilized in TPP. Canada is one of those partners too. So in essence Odumbo gave powers to other trade partners of the Pacific Rim nations to sue in court fr breach of contracts when the one party performs needless delays that reflect careless neglectful hardship on free trade partners. Basically Keystone will win and the US will have to pay the 15 Billion.
