That's how long they tried.
Again, we LEFT, that's different than they beat us militarily, if Trump didn't sign that deal to try and save his career, we will still be in Afghanistan, we don't have plan to annex Afghanistan as 51st States, which mean at some point in time we will have to go.
I would like to see how China can even sustain a war that far for that long, people like you know shit about Military didn't even see that the deployment distant itself is a major challenge, we weren't native in the Middle East. Which is the reason arguing with you lot is doomed to begin with.
