I'm going to go out on a limb here and say meeting with war criminals at the behest of an unknown benefactor, without telling anyone you're doing so, is a definite "minus" going into 2020
The US government has been just as big a war criminal as Assad.
No. It's really not.
As someone who spend a good year or so on the whole 'US Empire' bend I know it's factually untrue to claim that the US is a war criminal on Assads leave. The US hasn't used chemical weapons on it's own people multiple times, or caused half the country to flee, or bomb hospitals and schools with barrel bombs
