US-backed militia groups now fighting each other in Syria

Yes. Our big brother world police policy is terrible. We train and arm groups to fight based on our interests or for the lesser of two evils, then they turn around and start a new cycle. It's like buying a car, terrible investment and a money pit. We should focus efforts on keeping our streets safe as well as borders before we go elsewhere. Did I stay on topic?

Though I don't limit this question to this administration exclusively, didn't we have similar problems in Egypt, and Libya as well?

SSG Gerhard S. There is a struggle for control (leadership division) within the groups. A key figure,for lack of a better term, began a "McCarthyism" campaign. His actions created division and distrust within the groups and between them.
