If only he had kept U.S. troops there a bit longer or even indefinitely, their argument goes, the crooked and corrupt U.S.-installed Afghan puppet regime could have won the war and finally brought "enduring freedom" to Afghanistan.

Never mind that the U.S. national-security establishment had twenty long years to achieve its goal of bringing a model society to Afghanistan. 

Never mind that U.S. officials sacrificed the lives of thousands of U.S. soldiers and hundreds of thousands of Afghans in their quest to bring "democracy" and "enduring freedom" to Afghanistan.

Never mind that U.S. officials spent around a trillion dollars in U.S. taxpayer money on their intervention, much of it ending up in the personal pockets of their crooked and corrupt Afghan puppets. 

Never mind that the Trump administration entered into an agreement with the Taliban to exit the country last May. Given that Biden unilaterally broke the agreement by extending the U.S. exit to September, the dead-enders argue, he should have just broken it even more by extending the exit date another several months or perhaps even indefinitely into the future.

The defeat of U.S. forces in Afghanistan, after 20 long years of massive death and destruction, provides the American people with an opportunity to engage in some serious soul-searching as to where we are as a nation and we should go from here.
