Except with a lot lower casualty rate. Strategy Page says that the Iraqis are finally getting fed up with the violence:

American military commanders and diplomats continue to remind Iraqi politicians that the biggest problem in the country is corruption. That’s hard for many Iraqis to accept, since stealing whatever-you-can-get-your-hands-on has been a tradition for so long. Many Iraqis assume it’s the natural order of things, and consider the Americans insane, or disrespectful, with all their talk of honest government. The message, however, is getting through, as it becomes obvious that Iraqs new democracy won’t work with the traditional Iraqi attitudes towards dishonesty in politics. This new attitude is being reflected in many ways. There are more corruption investigations, arrests and prosecutions. The corruption is still there, but it’s becoming politically incorrect. Meanwhile, everyone is getting more patriotic. It’s no longer cool to take orders from Iran. So Muqtada Al Sadr, and his Mahdi army, are becoming less a tool of Iran, and more a mainstream Iraqi political movement. Sadr is even sitting down and cutting deals with Sunni Arab politicians. At the same time, the Mahdi Army is being purged of factions that don’t go along with the new peace and reconciliation approach. Those radical factions are still killing Sunni Arabs, while Sunni Arabs and al Qaeda continue to slaughter Shia Arabs. This is not popular with Iraqis in general, and the terrorists are increasingly seen as a public menace that all Iraqis must unite to destroy.

We won Iwo Jima. Some will argue, of course, that the analogy is more apt than it seems, because it was an unnecessary battle. But that was only clear (to the degree that it is true) in retrospect, and there’s little point in carrying the analogy too far.
