Iran will do everything it can, of course, to assure that the Americans are as exhausted as possible. The Iranians have no incentive to allow the chaos to wind down, until at least a political settlement with the United States is achieved. The United States cannot permit Iranian hegemony over the Persian Gulf, nor can it sustain its forces in Iraq indefinitely under these circumstances.
The United States has four choices, apart from the status quo:
1. Reach a political accommodation that cedes the status of regional hegemon to Iran, and withdraw from Iraq.
2. Withdraw forces from Iraq and maintain a presence in Kuwait and Saudi Arabia -- something the Saudis would hate but would have little choice about -- while remembering that an American military presence is highly offensive to many Muslims and was a significant factor in the rise of al Qaeda.
3. Halt counterinsurgency operations in Iraq and redeploy its forces in the south (west of Kuwait), to block any Iranian moves in the region.
4. Assume that Iran relies solely on its psychological pre-eminence to force a regional realignment and, thus, use Sunni proxies such as Saudi Arabia and Kuwait in attempts to outmaneuver Tehran.
None of these are attractive choices. Each cedes much of Iraq to Shiite and Iranian power and represents some degree of a psychological defeat for the United States, or else rests on a risky assumption. While No. 3 might be the most attractive, it would leave U.S. forces in highly exposed, dangerous and difficult-to-sustain postures.
Iran has set a clever trap, and the United States has walked into it. Rather than a functioning government in Iraq, it has chaos and a triumphant Shiite community. The Americans cannot contain the chaos, and they cannot simply withdraw. Therefore, we can understand why Bush insists on holding his position indefinitely. He has been maneuvered in such a manner that he -- or a successor -- has no real alternatives.
There is one counter to this: a massive American buildup, including a major buildup of ground forces that requires a large expansion of the Army, geared for the invasion of Iran and destruction of its military force. The idea that this could readily be done through air power has evaporated, we would think, with the Israeli air force's failure in Lebanon. An invasion of Iran would be enormously expensive, take a very long time and create a problem of occupation that would dwarf the problem faced in Iraq. But it is the other option. It would stabilize the geopolitics of the Arabian Peninsula and drain American military power for a generation.
Sometimes there are no good choices. For the United States, the options are to negotiate a settlement that is acceptable to Iran and live with the consequences, raise a massive army and invade Iran, or live in the current twilight world between Iranian hegemony and war with Iran. Bush appears to be choosing an indecisive twilight. Given the options, it is understandable why."
