Scary stuff. There is no doubt that Bush & his fellow loonies are capable of carrying it out. They have proved that they are incapable of considering consequences. The thought of a million or so vapourised Iranians wouldnt trouble them one iota. But the fallout should: "This small expansion of the Pentagon franchise would result in stellar production figures: three million people killed by radiation in just two weeks, and 35 million people exposed to dangerous levels of cancer-causing radiation in Afghanistan, Pakistan and India." Now Pakistan and India are nuclear powers - what will they do? Russia and China -they have nationals working there and $hundreds of billions invested in infrastructure- they wont take it lying down.
Whoever drops the first nuclear weapon on Iran, whether it be the US or Israel, will regret it deeply.
