France is unhappy that our intervention in Syria isn't also targeting Assad:
France is calling for the U.S.-led coalition against Islamic State to expand its fight to prevent the fall of Aleppo, Syria’s largest city and a rebel bastion under attack by both government forces and Islamic extremists.
Coming from a key ally, the push for increased military support for Syria’s embattled civilians and rebels is a public challenge to President Barack Obama’s policy, which limits military action in Syria to attacking Islamic State fighters while avoiding direct confrontation with forces loyal to President Bashar al-Assad.
That's been my main complaint of our Iraq and Syria strategy at the big picture level.
Stop whining about the weakness of the moderate opposition that we refuse to support robustly. If we give them real support, they'll become the strong horse in the fight against Assad.
