>> for a pathetic agreement with Iran.

I couldn't disagree more.

Yes, the odds are not great that the agreement will succeed, but it might.
Taking long odds for peace doesn't get you any medals or ticker tape parades but it can save lives.

I find a parallel in the crappy armistice that Ike agreed to with China and North Korea in 1952.
For over 60 years now, our troops have been eyeball-to-eyeball with people trained to kill them.
It's a tissue-thin truce that could explode in a minute.
But it hasn't.
We haven't lost any people there and the people of South Korea have created one of the most progressive societies in the world.

Why did Ike make that crappy truce when at the same time MacArthur wanted to invade Manchuria and defeat the Chinese?
He said it in his epic Crusade in Europe:
"There is no glory in battle worth the blood it costs."
