One bad act doesn't justify another one. So to simplify: apparently us troops are in Syria to support their fight against terrorism ( which we all know is not true cuz the very same US government founded and still funding ISIS so they can put Syrian  banking system into IMF which is owned by Rotschilds and Rockefellers) even tho if that was true ,why would we "light up " Syrian airbase that helps in fight against terrorist ??? If you read European media you'll also see that for all these years we haven't done any good in Syria,as a matter of fact there are proves that we are giving weapons to terrorist ,but our government won't let media report that.
