In this approach, the United States would dramatically reduce its military footprint in the region, leaving only the bare minimum of the current arrangements in place. The headquarters of the 5th Fleet would remain in Bahrain (where a U.S. Navy flag has been welcome for 50 years), but fewer American warships would ply the waters of the Gulf. The air force would retain its huge new base at al Udeid in Qatar, again because the Qataris seem pleased to have it there. The army might keep some prepositioned equipment in Kuwait and Qatar and might regularly rotate in battalions to train on it -- if those states were comfortable with such guests. In addition, if a future Iraqi government were amenable, the United States might retain an air base and some ground presence there. Alternately, army bases in the region might be dispensed with altogether, and instead the United States could simply rely on equipment stored on container ships stationed at Diego Garcia, in the Indian Ocean.
On the political level, the United States would preserve its informal relationships with the GCC states and possibly add a similar association with a friendly new Iraqi government. It would continue to contain Iran by making clear that any Iranian aggression would be met by an American military response. And it would continue its efforts to secure European, Japanese, and Russian support in pressuring Tehran both economically and diplomatically so as to end Iran's support for terror and its unconventional weapons programs.
This smaller military footprint would go a long way toward alleviating the internal problems caused by the presence of U.S. combat forces in the Persian Gulf region -- so not surprisingly, this is the strategy that the Gulf Arabs themselves favor. With Saddam gone, their overriding goal now is to minimize domestic discontent, and they believe that the United States can keep peace in the region with a minimal presence. This approach would also be popular in certain quarters of the American military, which would be glad to shed the burdens of policing an inhospitable and less than luxurious region far from home.
