Removal of Assad first, then eliminating ISIS: U.S Senator Nelson
"The U.S. Senator added that the situation in Syria is very complex because the plan of arming and training the moderate rebels includes only a few hundred fighters, who bear the responsibility of fighting the Islamic state, while they fight the Syrian regime’s army, and the allied Shiite militias all at the same time.
He stressed that the United States should provide qualitative weapons to the moderate opposition forces to be able to change balance of the battle on the ground, and that it should seriously work to remove Bashar al-Assad from power."
