If this isn't a clear sign that USA supports and fund ISIS, I don't know what is.

We are deliberately trying to save and rescue the last stronghold of rebels until we can form a coalition to invade Syria with Saudi Arabia, Turkey, and Qatar.

they are funding ISIS not 'tipping them off' they funnel the cash through Saudi and Turkey - it's all fake Oil dollars -

actually the whole Mid east is at stake - the USSA (and proxys) is so over extended it may be rolled back like a domino set.

Russia shouldn't accept pretty much any ceasefire until enough DAESH is removed that it could be beaten by a single battalion in direct face-to-face combat... by the nation that lost to the Emus.
