I believe in the very near term, we will be financing the Taliban, these weapons were left behind on purpose to be used in the future...
Since the US is leaving Afghanistan I’ve seen articles on FreeRepublic about how the Chinese will reap all the mineral reserves of country....in order to do that China will have to import a lot of Chinese workers.....
The weapons we have left behind and the money we will be sending the Taliban will be used to bog the Chinese down in Afghanistan just like it was against Russia in the 1980s when we sent money and Stinger anti-aircraft missiles to the Mujahedeen
I did a quick search to find out what might be in that God forsaken corner of the world. I figured nothing but it seems the Afghanis are sitting on some pretty valuable resources such as copper, iron, sulfur, bauxite, lithium, and rare-earth elements.
All found and proven by the USGS since 2005.
