This is good news. Now, Russia and China can cooperate, and control if necessary, Iran. The U.S. can let well enough alone, Iran's loose cannon of a President can derail his support amongst Iranian youth and Iran can slowly fade off the screen.
It won't happen but it is pleasant to consider.
The biggest threat from Iran is in conventional weapons, gun-running, and embarrassing itself in world affairs, but, we already knew that.
This is business as usual.
I find that it is a relief to discover that Iran did not develop nuclear weapons for some time. In the rush to laugh at Bush the world can breathe a bit easier and continue to oppose the Iranian regime.
