Biden just declared to the press that Afghanistan will have to take care of itself and that the US did not enter Afghanistan to nation build, as we read in the New York Times:

The departure of American troops has been accompanied by reports of increasingly dire situations on the ground as local government forces crumble before the Taliban, which is gaining territory as it nears Kabul, the capital. In the span of just over two months, the Taliban have managed to seize at least 150 of Afghanistan’s 421 districts.

Questioned on Friday about the risks of the accelerated pullout to the stability of the Afghan government, Mr. Biden said: “Look, we were in that war for 20 years. Twenty years.” He added, “The Afghans are going to have to be able to do it themselves with the air force they have.”

But pressed to elaborate, the president cut the reporter off, saying, “I want to talk about happy things.”

America’s withdrawal, as well as its departure from Iraq and Syria, reflect the trend of American isolationism.
