Appeasement, or Collaboration?

Bookworm Worm has a different take on Obama's deal with Iran:

So why did Obama give away everything when he didn’t have to give away anything? This is not appeasement; this is collaboration. As Obama made clear from the beginning of his administration, he wants to side with the mullahs and he doesn’t like Israel. Obama has now given free rein to the Obama doctrine: the elevation of Islamic totalitarian dictatorships to the detriment of anything that stands in their way. This manifestly awful agreement isn’t a desperate mistake, it’s an intended outcome.
