This. Wish i could upvote 10x. When the negotiations are secret, it's one thing. When the agreement itself is secret for longer than a (usa) president's term, that's another.
It's the draft that will be secret, not the final agreement.
I don't understand why this is so confusing: It's much easier for negotiators to propose a series of concessions and trade-offs in private, knowing that they'll only face political heat for those that actually make it into the final agreement.
It's also much easier for them to propose a series of trade-offs and concessions that primarily benefit their rich donors/friends rather than their electorates.
