I am all for Israel retaliating. I am glad they did. However, I am concerned that a weakened Assad means a stronger ISIS. It would be nice if the Israelis hit an ISIS target or two as well.
The more they kill each other, the less we have to deal with. Hopefully they'll thin themselves out.
Arm both sides equally. If one side gains an advantage, arm the other side just a lil bit more. Rinse/repeat.
