How difficult (and costly) is it to stop it at its source versus at our shores? Afghanistan is about the size of Texas, but it doesn't have the infrastructure, i.e., roads, airports, rail, etc., to facilitate efforts to destroy the poppy fields and distribution system. And the Afghan government is corrupt, which doesn't make them a good or willing partner to eliminate the source.
Yeah I get it but letting the corrupt
CIA distribute the drug worldwide is hardly an answer.
