Here's part of a comment from a Brookings institute representative. They are refusing to give Biden credit because they don't think he deserves it
Both Netanyahu and Biden would love to have the overthrow of Assad be part of their legacy because it would be viewed as an accomplishment. Do they deserve it, in your mind Netanyahu seems to at least. I would rather not give either of them credit for anything. I think credit should go to the Syrians“It is probably untoward for the Biden administration to take credit — it was ultimately Syrians who took the actions that freed them from this brutal regime.”
“There was no evidence of a wider U.S. strategy that was aimed at the outcome that we have seen in Syria over the past week,” she concluded. “Washington took its eye off the ball in Syria many years ago.”
