They should get it

Heck we should make a courty out of that land

Can Afghanistan even govern itself?

It did beat soviets

Afghanistan did?
I think American government and military, and Pakistani government and military trained and funded a group called the "Mujahideen" who did that. Afghanistan government was kinda out of the question, it had no power alone.

America did support it, but Afghanistan managed to stay alive which killed 250k USSR troops I think

They managed to stay alive, of course.
Now, what area of land are you talking about here?

Pakistanian-Indian land dispute

Kashmir.
Don't you think there should be a referendum there? The people should vote for what country they want to join or if they want independence. That's what the U.N has asked for.

or split the land in half and give it to both sides

oki then
