Should the U.S. work more with Bashar Al-Assad in the fight against ISIS?

Quite tricky choice here. Should the U.S. accept Assad and allow him to remain in power in the coalition against ISIS? Or should the U.S. still work for the removal of the Assad regime while simultaneously targeting Isis?

We allow him to remain in power - what is the other practical option, unless we go in there with guns blazing and help ISIS take over?  That does not mean we have to treat him as a partner in a coalition and give him any direct help.

Generally most of you underestimate how destabilizing this conflict, this is a conflict that needs to end ASAP and this obviously require that one of the parties win.

Also, forget about Russia in this context, it is utterly irrelevant compared to the severity of the situation.

A Russian army presence in Damascus makes removal of Assad impossible. Assad has killed and tortured more civilians during this civil war than IS and Al Nusra put together. He is the destabilizing element in the country, and should be removed, preferably on a timeline. Not to mention, Russian presence also impedes effective operations of a US Army intervention against IS, when or if US intervention against them ever becomes a necessity.

Putin knows all of this, which is the only reason why he suggested it.

How would Russia fighting ISIS get in the way of the US fighting ISIS?
