The U.S. invasion and aid for terrorism is not based on the UNSC resolution 2249, dumbo. And everyone knows they aren't there "to fight ISIS" et all, you have to be really dumb to believe anyone in this age seriously believes that propaganda narrative. Selectively bombing a single group which U.S. backed terrorism has willfully allowed to spread in first place only in certain places around oil fields important to the Syrians, only to occupy them while ignoring the terrorist in any other place where attacking them could actually stabilize Syria, doesnt make the U.S. invasion compliant or even related to the UNSC resolution 2249. Arming and training terrorist to undermine and overthrow the Syrian government and occupying Syrian assets directly and via directly controlled illegal militant proxy groups and directly attacking the Syrian government forces to support terrorists, has nothing to do with the UNSC resolution at all either.
In fact the acts of the U.S. willfully directly and indirectly supporting terrorist groups and terrorist acts goes right against the UNSC resultion which demands to prevent and suppress any terrorist attacks in Syria, which the U.S. clearly doesnt give a shit about, in compliance with international law, which the U.S. clearly doesnt give a shit about either.
Obviously an anoying realty to lying terrorist sympathizers.
