Educate yourself . Give your advice a try . The U . S . is not trying to outright destroy ISIS , in fact the U . S . main concern in Syria is Assad . The U . S . armed rebel fighters , which some turned out to be al qaeda and even probable that ISIS received U . S . funds and weapons early in the conflict . Currently the U . S . uses a funneling strategy to funnel ISIS towards Assad forces , ISIS is being used as a tool by the U . S . against Assad . This is why Russia and the U . S . are at odds over Syria . The U . S . attacks ISIS and pushes them away from U . S . backed antiAssad rebel groups . Russian then attacks ISIS when it attacks proAssad forces . Sure the U . S . is striking ISIS , but not when it ' s politically inconvenient for them .
