Baathists like those have not only simply 'joined' with Islamist groups like IS to reinforce their insurgency. They actively set them up. The group's original name ISIS or ISIL, meaning 'Islamic State of Iraq and the Levant,' refers to the Sunni majority area across Iraq and Syria, which they now control.
The administration's Iraq policy has failed. The U.S. is more entangled in conflict and war; Americans have been killed in retaliation for Washington's intervention; the Islamic State is still advancing; U.S. allies continue to free ride on America; Washington hopes to square a nonexistent circle in Syria.
These are problems that can only be fixed with more funding and resources, and now is the time to respond. Not only are the displaced battling to survive each day, they don't know how long they can stay wherever they are, if they will need to flee again or if their lives will ever return to normal. When and how this ends, nobody knows. What we do know is that humanitarian aid is desperately needed to keep people alive. The road ahead is long and the international community needs to step up now to save Iraq before it falls beyond repair.
American intervention has broken pottery all over the Middle East. Every time the U.S. attempts to repair its last accident, it increases and spreads the mess. It is time for a different approach. One in which Washington does not attempt to micromanage the affairs of other nations. In which Washington practices humility. This would not be isolationism. America, and especially Americans, should be engaged in the world. Economic and cultural ties benefit all. Political cooperation can help meet global problems. Humanitarian needs are varied and manifold. Military action sometimes is necessary, but only rarely -- certainly far less often than presumed by Washington.
