I don't know who's setting these fires, but I do know that the US still maintains 7-8 military bases within Syria's borders as it continues its campaign to force out Syrian President Assad. When the Syrian conflict was raging on a few years ago, these US bases were launch points for bombing attacks on Syrian infrastructure. That's right - the US was bombing Syria from within its own borders! The bases also provided ISIS with direct air support, special forces support, and logistics support. Most of the propagandized American public thought the US was fighting ISIS, not supporting them. BTW, I'm American, not a troll, just the truth.
