Why did joe Biden remove troops please explain very briefly no without any bs

honestly he really shouldent have but i guess he thinks the afgans can hold their own which they cant

Explanation:

He thinks that removing is safer for both parties, but instead, the talibans and a few roaming clans are starting wars to claim the land we left. Now Afghanistan is now really mad, which is creating more hatred and reason for terrorism.

This is as much info as I can provide, since we`ll never really know why he would do such a thing.

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.
