Imagine, if you will, an alternate timeline. One in which Biden decided to remove all weapons from the Afghan military during the pullout.
The Taliban takes control. Immediately, Biden is blamed, and for good reason. The US had propped up a foreign military for YEARS, and right when we leave them to defend themselves, we take away the weapons that we had trained them to use. A massive military embarrassment. Conservatives immediately pin the Taliban's rise on Biden - he is labeled a traitor for betraying our foreign allies and removing their only hope to stop the Taliban.
Conservative memes blame Biden for the Taliban's rise and accuse him of being a traitor, perhaps siding with the Taliban himself.
