According to CNN, "the US is confident of Iran sanctions". I wonder if that confidence extends outside the Bush Administration and those who serve "at the pleasure of the President"? What ace in the hole can they have with regard to Russia and China?
I've said before regarding India and Pakistan that their acquisition of nuclear weapons was what earned them respect on the world stage, which led to a cessation of hostilities in Jammu & Kashmir. Now Idon't want any nuclear weapons, let alone more of them in more people's hands but the results were there for all of us to see.
So now, Iran wants respect -- not to mention another source of energy. And China and Russia desperately want a way to look like they're a counter-balance to what is perceived as American bullying without themselves looking belligerent. And they're going to fail to veto Security Council sanctions against Iran? Somebody's dreaming here.
I have only one thing to mention to the US: what happens when you attack a tyrant? He becomes a hero in the eyes of his people. Then you have to destroy his country to depose him. Remember Saddam and Milosevic and find some other way to "deal" with Ahmadenijad than finding another "coalition of the bought" and sending in your invincible military machine. This is not a game of Risk. People's lives and the longterm habitability of large pieces of the planet are at stake.
