The front-page New York Times story today on the role that Iraqi financial instituions are playing in helping Iran to evade sanctions may well be taken by opponents of the decision to invade Iraq as vindication of one of their core arguments: namely, that Saddam Hussein was a vital bulwark against Iranian power and that toppling him would only increase Iranian influence in Iraq.
How much of a bulwark Saddam actually was is debatable: The Iranian Revolution spread its influence for decades to Lebanon and Syria, among other places, all the while Saddam was still in power. That Iran has managed to increase its influence in Iraq since 2003 is incontestable, however. To some extent, Iranian influence in a neighboring state is inevitable. The situation has gotten worse, however, because of a series of bad policy choices made in Washington.
