Are we going to loose the war in Afghanistan?

It's "lose the war" not "loose" the war and, yes, we will - just as the Russians did before us and the Brits before them. We'll lose it for all the reasons you mention, and a few more. As for what America will do after this outcome - I think we will walk away from it. It's hugely unpopular at home and we need to cut our losses and leave.
