As mentioned in other posts, we are not completely innocent in our dealings with Persia.
What is in it for us, reducing centrifuges, reduction on uranium and the capacity to enrich, and a reduction of plutonium. What is in it for the hardliners but more war and mismanagement. Christ, we make foreign policy based on the wishes of another nation state, that is f*cked up. Who gives a fat sh*t what Bibi and his ilk like, they are not drivers of our security policy.
