Years of hard work by the MEK, their lobbyists, parts of the Israel lobby (esp. when it overlaps with the anti-Iran lobby and the neocons) have finally borne fruit. A rather strange, cultish organization that once bombed Iran's parliament is no longer on the US list of designated terrorist organizations. It comes at the time of the most concerted effort to put pressure on the Iranian republican regime since its creation, and with much talk of war as background chatter.
There's an aspect of the delisting of the MEK that may have some merit: the refugee issue, i.e. where resident of Camp Ashraf might end up because they're no longer welcome in Iraq (as they were under Saddam Hussein, and ironically aren't under the Iran-leaning Iraqi government that the US overthrow of Saddam made possible.) But it shouldn't overshadow the many other reasons the MEK — a fundamentalist guerrilla movement, essentially — will now make a handy recipient of US (and other) funding should things continue to heat up with Iran. Or indeed the story of how this was possible: perhaps not so much because geostrategic calculations as intense lobbying and a lot of money.
