I am betting on number three. They are hell bent on their third war in Iran....
US vs. Iran: Is an attack inevitable?
<snip>
US Options
No US administration has ever damaged United States’ interests so heavily and in such a short time as Bush’s administration. This administration has managed to alienate over 1 billion Muslims around the world. It has alienated Europeans, Africans, and Asians. It has used threat of force to force nations into submission, and instead of wining friends has created enemies across the globe. Russia, China, Iran and Venezuela are just to mention a few countries, out of fear (for details read “Cold War II”) are trying their utmost to make sure that US doesn’t get any stronger.
This has left US with few options. Having destroyed the balance of power in the Middle East, it is left with either accepting the new arrangement, or throw the whole world into an unimaginable economic chaos.
US has three options: (1) Withdraw from Iraq, (2) make a grand bargain with Iran, or (3) attack Iran.
1. The first option is a huge strategic defeat for the US; something that will affect all the countries in the Middle East. A US withdrawal is tantamount to a defeat. The US clients having backed the US against the will of their populations will have to make a U-turn making similar security deals with Iran, ensuring an even greater strategic rise in the Iranian power.
2. US can not/will not come to terms with Iran. United States, after spending billions of dollars, not to mention the thousands of American dead and wounded wants to have economic and strategic compensation. Iran does not accept US hegemony and demands security guarantees from US that it will not in the future invade Iran; something that US doesn’t want to give. There is also the matter of Israel. Iran has become the centre of the Islamic and Arab world. Muslims now look to Iran to protect the interest of the Palestinians. A grand bargain would also mean that Israel has to vacate the occupied lands and return to its 1967 borders, something that the US Jewish lobby does not accept.
3. This leaves US with only one choice: weaken/isolate Iran first (if possible) and then attack it. All the talk about NPT and uranium enrichment etc is geared towards this end.
