the "obvious" Iranian links

""There's little chance that al-Sadr will ease his demands that the Pentagon stick to its timetable to withdraw all troops by the end of the year. And his Iranian links are obvious. At a speech in the Shiite holy city of Najaf, his guards wore Iranian style outfits: identical gray suits with shirts and no ties.""  By the way, I should come clean. I never wear ties: does that mean that I too have Iranian links? (thanks Nicholas)
