Afghanistan now joins a very big club, including Venezuela, Cuba, Iran and others, of those the U.S. aims to starve into regime change. How's that going? Well might you ask. It appears to be utterly ineffective at anything aside from tormenting ordinary people. In the face of sanctions, leaders clutch at power more ferociously than ever, because they see themselves endangered, while cancer patients can't buy chemo.  In short, these sanctions will break Afghanistan financially, probably cause famine and will doubtless engender huge emigration, while serving no purpose besides random cruelty, because sanctions are war by economic means. The analogy is a medieval siege. Sanctions prove that Washington isn't done with Afghanistan, just as the bloodshed on the eve of departure did.
