1) turkey hates kurds, meaning strong motivation to silently support enemy of them (not calling them outright allies). let them bleed so they are weak and don't dream about kurdistan covering turkish soil. 2) US-led precision strikes achieved next to nothing, ISIL was strong as before. At one point US boasted that they spend 9 millions of USD daily for these strikes. That means an attempt to bring down organization of a size of state with few plane flights a day and couple of bombs? Not working. Of course I am not a fan of cluster bombing vietnam-style either. 3) it seems to me, and in this I might be wrong that US has higher priority in bringing down Asad rather than ISIL. So similar approach as 1) 4) the simple fact that ISIL is daily trading oil using big oil convoys means either US is completely incompetent to see this & take action (not believing for a second, ac-130/a-10 would squash them in no time), or that russians are much much better than US at surveillance from above (not a chance) and one could go on and on...
