It is unlikely that George W. Bush feels constrained by international law when deciding whether to use military force abroad. Nevertheless, many of the United States' allies are reluctant to cooperate with and participate in military actions that cannot reasonably be justified under international law. And supportive allies, while perhaps not strictly necessary to the United States in its recent and foreseeable military campaigns, do make the military option easier to pursue. A war against Iraq would be difficult without access to bases and airspace in countries as diverse as Turkey, Saudi Arabia, Germany, and Canada. For this reason, at least, it would seem to be worth the president's while to adhere to international law where possible and, where this is not possible, to seek to change the rules.
International lawyers in the Department of State, together with lawyers in other parts of the U.S. government, have excelled in shaping the law to accommodate the interests of the United States. One example, though by no means the only one, concerns the response to the September 11, 2001, terrorist attacks.
