But petrostates are unlikely to be good allies for the U.S. campaign in Iraq and Syria. The reliance of those countries on oil and gas revenues distorts both foreign policy decisions and their implementation. First, petrostates have weak foreign policy institutions, producing policy that is of poor quality and strongly driven by personalities. Second, the vast flow of oil income enables the states to back nonstate actors in conflicts, but their weak civil service cannot control the flow of arms or funds. Third, oil income also enriches private citizens, some of whom directly fund terrorist organizations such as ISIS. Thus, largely through ineptitude, those states have helped to foster Syria’s civil war, indirectly facilitating the rise of ISIS.
The idiosyncrasies of oil‐rich states make them poor partners for the United States in this instance and in future conflicts. As allies, petrostates are especially likely to draw America into unnecessary and intractable conflicts. In particular, Washington should largely disentangle itself from the Saudi alliance and from reliance on Saudi intelligence and diplomatic services. Keeping Saudi Arabia at arm’s length will help to minimize involvement in Middle East conflicts that are not vital to U.S. interests.
