Biden did no such thing.
Instead, he green lighted the Taliban takeover and enabled their victory.
The Taliban never would have made a run at Kabul if the US had not sabotaged and undermined the entire Afghan government and military and made it clear they were abandoned and helpless.
The Taliban were stunned at their sudden success. They should be because nobody could have expected that the US would hand them the keys to the country.
The big winner here is China and they are going to use the demand for rare earth minerals generated by Biden's infrastructure and Green Economy initiatives ( which will use 90% Chinese made goods ) to develop and exploit Afghanistan's mineral wealth and enslave the Afghan people for the benefit of the Taliban overseers and China.
We have watched this play out in Africa and there are no worse exploiters than the Chinese. The European colonial powers were enlightened and benevolent compared to the Chinese.
That's only half of it. The Afghan military and government were hopelessly corrupt.
They had 20 years and 90 billion dollars to get it straightened out and they didn't.
