Just like Iraq?
Yes Panzer , like Iraq its another lost war .

The Taliban has no control over anything
Actually its the colilition and government in Kabul who control very little and are losing that little steadily .
Whats it down to now ? less than a third of the country

The US military has heavily armored humvee convoys driving around southern Afghanistan as we speak looking to provoke Taliban attacks just to crush them.
Sounds like Vietnam eh

The goal is - and should have always been - to keep the Taliban out of power.
Which you ain't doing .

The best option would have been to prop up a relatively secular local strongman
Like a Saddam ? Then again you do have Dostrum , a nice ally who changes allegience more aften than a hermit changes his robe and doesn't give a damn about anything apart from making money from the opium trade .

There is absolutely no way they will be able to retake and hold land any longer than the US allows them to.

They don't have to , all they have to do is wait .
