EXCERPT:
MADDOW: "If this works, no war with Iran. And it also means no nuclear bomb in Iran. And it means this President will have achieved the only diplomatic, world-transforming achievement big enough to make us forget all about him, also ending 50 years of cartoonishly failed and ridiculous U.S. policy toward Cuba, which he also did a few minutes ago. We don't know if the Iran deal is going to work. If it does, it will be the major foreign policy achievement, not only of this presidency, but of this American generation. At which point, people in the not too distant future will look back at this presidency, they'll look back at this President and they'll say of course they gave him the Nobel Peace Prize, of course they did."
