Godforsaken land
I believe Alexander the Great was the only one who succeeded in conquering this land, and even he didn’t stick around very long. The British tried several times and failed miserably. The Soviet armies later met their match in the mujahideen. America has wasted 20 years there and several thousand of our soldiers have been killed by roadside bombs, etc, with no measurable progress in this endless war.
Either get out now, or greatly increase the number of troops with the goal of destroying the Taliban and ISIS. Those are the only choices.
