Is Joe Biden to blame for the rebels' advance on Damascus?

Assad was doing so well. He practically won, now out of nowhere the rebels have advanced on the Syrian capital, the Syrian military has fled into Iraq and Assad is nowhere to be found.

Is Joe Biden to blame for the rebels advance on Damascus?

I think Biden is indirectly, because Assad's three most powerful allies Russia, Iran and Hezbollah are all pre-occupied with other wars that were started because of Biden's weak foreign policy leadership

I knew January 20 is too long to wait. I knew Biden would still mess something up before leaving.
