When it came to the withdrawl Biden put the cart in front of the horse.
I mentioned this last year , or it may have been the earlier : Afghanistan probably should have been split along ethnic and sectarian lines, creating either seperate countries or autonomous zones, like how we created an autonomous zone for the Kurds in Iraq. Because the Taleban gets the lion share of its soldiers and support from Pashtuns. Sun Tzu said something along these lines: the rebel is the fish and civilians are the sea. The rebel can not survive without a sympathetic civilian population. While there were Pashtuns who fought against the Taleban, and warlords switched sides , for the most part the Northern Alliance were non-Pashtun and the Taleban are Pashtun. Back in the late 90s or early 2000s, Janes Defense Weekly carried an article on the Taleban and their harsh rule. In the article , Muslim intellegensia claimed the Taleban weren't about Islam, it was pre-Islamic tribalism masquerading as Islam.
I used to live in Arabia, a long time ago; there is a famous saying: me against my brother, me and my brother against my cousin, me and my cousin against the world. Afghanistan isn't Arabia, but the sentiment holds.
Maybe we should have just aided the Northern Alliance to conquer territory and defeat AQ and the Taleban on the battlefield, and not attempted to occupy and create a functioning democratic government. The US has no problem winning wars when the combatants are identifiable, the problem starts when combatants dress like civilians and melt into the civilian populace, because our rules of engagement, respect for human rights, the Geneva Convention and humanistic society won't allow for the kind of war the Chinese would engage in to defeat such an enemy.
