Dual containment is a risky strategy that relies on a vast and precarious network of alliances, assumes Washington can restrict Iranian and Iraqi military buildups, and requires a prolonged U.S. military presence in the Persian Gulf region. Yet the United States has no vital interests in the area to justify a policy that is so costly and entails so great a risk of drawing America into regional conflicts.
If dual containment succeeds, even partially, in isolating Iran and Iraq, the consequences for the United States may be grave. An anti-U.S. alliance between Tehran and Baghdad is not inconceivable. And in the event of either regime’s breakdown, many forces in the gulf region will seek to exploit the ensuing chaos, making a regional war–which the United States will have little hope of avoiding–nearly inevitable.
