The Russians & Iranians are arming Assad. So, unless the resistance gets help, (& it doesn’t look like they will) it’s going to be over soon.
The White House is stalling, hoping it’s over soon so they don’t have to get involved.
The White House won’t step in this time because those fighting are actually REAL “Freedom fighters” and NOT a planned overthrow by the Muslim Brotherhood. THAT’s why Obama will not even say one word about this. His blind-eye is already turned on these people as they actually believed the propaganda of the “Arab Spring” narrative, naively believing Obama’s administration would actually HELP them rid themselves of Assad and his government.
I believe this “revolution” is already over - much like all of the attempted resistance movements among the Iranian people over the last few years. Like you and others have pointed out, the Syrian Gov’t is being armed by Russia and Iran - both obviously have a vested interest in Assad’s admin. remaining in power. These people are unfortunately “on their own” with the exception of God Himself. The only thing the rest of us can do now is pray for the innocent and good among them, frankly. I honestly can’t imagine what it would be like knowing your own government is the one shelling your city...
