I'm a liberal person, but I think Taliban takeover is a horrific outcome. What's the argument / angle here?
Furthermore, it seems to open the geopolitical sphere for China to step into the vacuum. It gives them more people to sell to, and a broader Belt and Road. It's strategic for their exports, too. That seems to not be in the interest of the United States.
Also, US troops in Afghanistan are positioned close to the Chinese border, which seems like a thing the US would want in order to apply pressure.
What's going on? I don't understand the withdrawal at all.
