and when the time comes, it sure would have been useful not to have wasted so many resources and international goodwill in Iraq

When Sunnis in Iraq and elsewhere start sending their youths to train at the new Somali terror camps (just like they used to do in Afghanistan, and still do in Pakistan and elsewhere) and those newly trained terrorists start showing up, and blowing up, anywhere and everywhere, it'll be time to rally another "coalition of the willing" to go and clean out the Islamist Somalia, in a very similar manner to Afghanistan 2001-present.

And only Allah knows how many times this exercise will have to repeated, again and again, in the decades to come, in the war against Islamic terrorism. And to be ultimately successful in the war, the civilized world simply can't afford huge, misguided screw-ups and setbacks like Iraq.
