It will likely drive Isis out of the desert and into the cities where it will find refuge among Sunni militants. Yes, it will degrade Isis but it probably will not destroy Isis because there will be no boots on the ground ferreting out these fanatics from every hole and corner in Iraq's cities. Later, Isis will emerge and resume its quest for a caliphate.
And they will use weapons we supplied to them through Syrian rebels - the cut outs.
ISIS is a conglomerate, backed by the Sauds. They are not going anywhere, other than the government centrals/entrails of their targets. The supposed targeted bombing, will actually help the bastards. Wake up. The latest version of socialist fascism is being promoted by Our- CIA, State Dept. and all of the Executive, Legislative and Judicial branches.
Guerrilla operations require local support. Liquidate the local Sunni Arab population, and that support goes away. This was how Saddam dealt with Shiite and Kurdish revolts. The Kurds and the Shiites will probably do something similar with the Sunni Arabs if GI's don't get involved on the ground.
Maliki was accused of being too sectarian. He wasn't really all that. Sure, he handed all the goodies to Shiites. But he really did not do much apart from turning a blind eye to very occasional Shiite militia attacks on Sunni Arabs. In contrast, Saddam killed an estimated million people to forestall plots against him. If some other country wants to play armed social worker, that's certainly its prerogative. I think we've wasted lost too many good Republicans and Christians in Iraq. It's time to let the natives do what they have to do. If Iraq's and Syria's Sunni Arabs have to find a new home in the gulf region, so be it.
