Hezbollah fighters do not represent a country. They are just members of Hezbollah, a sect in Lebanon. They are in Syria because they are being paid to be in Syria. Find out who is financing them and persuade them to stop. Then, no more Hezbollah in Syria. Or, probably, anywhere else, for that matter.

Better still, just kill all of them! Better, quicker, more permanent solution. The next stop should be Nasrallah’s compound for a “quickie” drone strike. The world for too long has tolerated this camel jockey trash.
