I understand the United States weapons once given to the Afghans are not OUR weapons anymore but their weapons. Plus many of those weapons given to the Afghans were already depleted or rendered useless during the war - which would be the vast majority as we were there from early 2000 until 2021. Spent ammo were not left behind but used. Destroyed weapons were not left behind but destroyed. I know this concept is difficult as it goes against your inbred storyline but we left little weapons behind.
