There may come a time to criticize the deal, but to do so now, when you know nothing, is just political partisanship. You are telling people that you hate the shit that will be served for dinner, when the table hasn't even been set.
Hell, Conor, a former freakin' marine, is hoping for a loss for the US. Shameful and embarrassing for him, and for all of you agreeing with him.
Wait and see, and if it is a bad deal, then criticize it. Until then, you are just making things up.
