Obama will simply not allow Israel under any circumstances attack Iran prior to the election. There is simply no consensus for another Mid East conflict for the war weary American people who simply do not believe that Iran is a real threat to the United States. Obama knows that in the event of an Israeli attack, the big blue water ships of the American navy are at grave risk in the narrow confines of the Persian Gulf. It would be a political and possibly a strategic disaster if any of those ships were to be lost. Despite sanctions and rhetoric, Obama has concluded that Israel will just have to live with a nuclear Iran and hope the mullahs are as deterred by mutually assured destruction as the Russians were. This defacto American policy as one may imagine is immensely disconcerting to Israel. It is very doubtful that Israel acting alone could be strategically effective and there is no doubt that Obama is making it very clear that the US will not get involved in a unilateral Israeli attack.
MAD had some teeth in 2000 when the US had 5000 warheads. We have been reduced to 1500 now. Obama wants that dropped to 300 or zero. We've been defanged by the muslim commie. Feel free to savagely attack the enemy with a big white feather.
