Well, what is support exactly? The UN had been on Saddam's case for over a decade. Sanctions didn't work. I doubt if these mullahs in Iran care very much about world opinion as long as it doesn't look like there's going to be a bottom line (forceable overthrow). The Taliban certainly weren't phased by world opinion. China doesn't care about it. Giving the Iranian opposition guns would seem to fit the bill of support to me. Pressure for the mullahs is having our military camped out next door or having an armed insurrection in Tehran, not a high school demo in Brussels.
