Personally I think this is about turning the screws on Iran and undoing the evil that President obama has done.
I'm seeing a real smart negotiation here, if the DC swampthings don't ruin it. Saudi Arabia needs a place to invest their money. The US needs that cash back for infrastructure. The tradeoff is that Saudis do what they do best....kill horrible people. In turn, the US has promised to not get involved in regime change or demanding that cultures change. And Tillerson has told the Iranians the phone is always connected.
I'm not sure Nikki Haley is on board.
I also think that Israel has to realize this is their best chance to make a deal. I'm wondering if part of that deal is no more settlements on Palestinian land, no more trying to overthrow governments, and they get to kill ISIS maniacs too.
