Now the same process may be occurring again in Iraq. A spurt of lethal violence this week between the Shia-dominated regime and a Sunni resistance has featured such war-like encounters as helicopter-borne government troops firing on a Shia village. This is another stage in an escalating confrontation between the opposing sectarian forces in Iraq. Again, there is no one point in the escalation at which anyone can declare that a civil war has now begun. But that does not mean one is not beginning.
Any new civil war in Iraq at this time would not really be altogether new but instead a resumption of the unresolved conflict that earlier reached a peak about six years ago. Resumption would be a reminder both of the overall results of the U.S. invasion and of the later surge of U.S. troops. We have known all along that the surge never led to the political reconciliation within Iraq that it was supposed to facilitate. Now we can say also that whatever improvement in security it fostered was temporary.
