Two pieces (somewhat long) lay out the reasons 1. there will be no grand coalition gathered against ISIS and 2. the competing goals of the relevant Middle Eastern nations.
Raghida Dergam The World Post The US president may decide in the end that this is not his war, and that it is best to return to his country to fortify it against terrorism, and let ISIS unleash itself on everyone until it commits suicide or until it is slayed eventually. This is perhaps the course he might choose if it appears to him that all those who want him to fight their wars on their behalf will meet his war with ingratitude and petulance.
David Stockman Contra Corner In truth, the whole thing is a giant, pathetic farce. There will be no coalition, no strategy, no boots, no ISIS degradation, no gain in genuine safety and security for the American homeland. This is an utterly misbegotten war against an enemy that has more urgent targets than America, but a war which will nonetheless fire-up the already boiling cauldron of Middle Eastern tribal, religious and political conflict like never before. There is no name for what Obama is attempting except utter folly.
Compared to the furrowed brow of American newscasters and journalists, these two pieces have a distant skepticism about the ISIS situation and the U.S. response so far. Note the competing and incompatible Sunni/ Shiite interests at stake. These make a grand coalition unlikely and as Dergam suggests it might also be the key to any small local coalition that would "degrade" ISIS.
