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...
Nations are simply pawns on the game table of the powers that be....while they fight those leaders barter for how each shall gain by who they defend. It's more than sad that people are dispensible but it is unfortunately the price when "freedom" is as is said...never "free".
This is not going to play out well by any stretch of the imagination.
