It makes perfect sense for the CIA to be attracted to Iran’s Baluchistan province. First, the area has well established drug smuggling routes--and the CIA has an insatiable hunger for profits to be gleaned from illegal drugs--and second Baluchistan is a neglected tribal backwater where Hanafi Sunni Islam has a foothold in contrast to Iran's Shia majority. In other words, Iran's Sistan Baluchistan province is a perfect place to stir up trouble and make some money for covert ops in the process.
As evidence the CIA has been busy at work in the province, back in 2002 the neocon-Israel friendly DEBKAfile reported "a CIA undercover unit has entered Iran through Zabul, in the Sistan Baluchistan province. Its assignment is to stir up dissent among the largest population in the area, the Baluchi tribes." Moreover, according to DEBKAfile, in December of 2001 "al Qaeda fugitives, including some 4,000 Saudis, began using these obscure [drug smuggling] routes on their way from Afghanistan and Pakistan to Saudi Arabia, the Gulf States, Lebanon and other points in the Middle East. The CIA's undercover unit has undertaken the tall order of closing this al Qaeda escape route, while gathering intelligence on its nefarious traffic." In other words, the CIA is working hand-in-glove with "al-Qaeda" (a term used to describe useful idiot Muslim fanatics and patsies), probably smuggling drugs and also importing "dissent" among the Sunni Baluchi tribes, who hate and distrust the Shia regime in Tehran.
