Of course, Israel will be the 'press release reason' but OIL is key. A nuclear Iran will gain hegemony in the Middle East. The US cannot afford that. At the same time, Sunni oil states will demand their own nuclear 'deterrence'. Thus, a nuclear arms race and nuclear prolifieration in the Middle East. If the US doesn't provide it you can be sure that Pakistan - France or China will. The next step is a nuclear war and with that the end of any oil production for months if not years. The US and the world cannot afford that. A world depression will follow. So, Iran will be hit to ensure that Oil continue but Bush will point to Israel as the reason when it's really about Saudi Arabia/Kuwait,etc.
