This is a story about how US deep state like CIA finance itself without congress or politicians approval.
They trade weapons for drugs . These drugs are sold locally in the US, money made are used to supply weapons to anti government forces in countries cia wants the head of state deposed.
I believe this operation is still active as can be seen the fentanyl " zombies " lurking in most citues in the US plus regime change operation have been scaled up by huge margin, mostly in the middle east.
