fight for what country ??? all normal definitions have broken down into murderous insanity...

There are some groups in Syria who only have Assad's regime to count on: the Alawites, Christians and Druze. The one thing that unites all the opposition factions is that they want those three groups exterminated (they'd want to exterminate the Communists as well, but they've probably all been killed by now). For them the definition of the country is the same as it always was.

For the US, Saudis and Israel, exterminating the Alawites was always the main point of starting the war, so they can get on with destroying Iran next. None of them give a damn what happens to the Christians and Druze in the process.
