You're correct. Unfortunately, trade agreements/pacts are just that and not "treaties". NAFTA was a trade agreement. It turned out to be detrimental to our economy and jobs, as Perot warned us. My problem is with the fast-track (TPA) authority given to any president that excludes amendments and filibuster from Congress.
However, a point could be made that the USA could rarely get any trade agreements done if left to Congress and their special interests. It's a conundrum.
I don't so much believe in free trade as much as I do in fair trade.
When you listen to Cruz and Ryan, they will invariably talk about the benefits of “trade”. What idiot is against trade? It is the corrupt trade bills we are all against, well, most of us. If you love Cruz, you have to flip-flop in order to justify Cruz’s support of Obama’s agenda.
