What is going to happen when we leave afghanistan?

After we send every available troop we can spare over there and eventually declare some sort of victory after spending trillions of dollars we don't have,what do you think is going to happen.I believe when we leave it will be business as usual for the taliban,go in, take over.I say get the hell out and let the afghans take care of themselves.They don't give a rat's a$$ about us americans so why should we help someone who would just as soon see us dead.We need to bring our troops home and work on securing the US borders to keep these turban wearing b-$tards out.What is your opinion on this matter?Thanks in advance for your answers good or bad,Ilike the bad ones,fun to read.
