Iran gets the sanctions lifted to the tune of $150B. They get to dramatically increase their oil exports which will dramatically improve their economy. They get to buy and sell conventional weapons. They got a key scientist released to them in April. They get to continue their nuclear program. They get to continue their support for terrorism. Assuming they don't cheat, they become a nuclear power in 15 years. If they do cheat, they become a nuclear power sooner. They get to keep the 4 American hostages.
What do we get? A legacy?
