American weapons sold to Taliban?

Is this gunrunning by the US?

Or is it just incompetence?

Corruption in Afghanistan. What a surprise!

Taliban buying US supplied weapons and FUEL from Afghanistan police and army. 

Is ignoring this part of a plan to foment further strife? Or is it being ignored in order to keep the programs in place so the suppliers can make more money(and kick some back to US interests….)? Shades of Vietnam style corruption here…..
