If you really think the US went all in on Afghanistan with a world war level effort to conquer the country then I don't know what to tell you. After the initial invasion period the country really was a sideshow and became increasingly less prioritized over the years. By the end of the occupation US forces had shrunk to a minuscule size compared to what an invading army would look like.

That doesn't mean that the war was handled well, it clearly wasn't. But looking at a small force and confusing that with the entire might of the US military is baffling to me. "Losing interest" is a perfectly reasonable description of what happened.

Now, now iraq and syria were pretty big defeats too. Red lines over which third world dictators stepoed pretty invurnerable.

For starters I would say that Afghanistan certainly lost. Taliban might have won but certainly not Afghanistan.
