the sanctions are actually too effective. they're so effective they've essentially turned one of the more industrialized countries in the region into a raw-materials starved inflation hell-hole for business. given a few more years i can't imagine iran existing still. most people stop blindly following their government BEFORE eating each other in the streets becomes a regular occurrence. and without half a century of indoctrination and political purges like north korea, they wouldn't have enough time to close the flood gates of revolution.
that said, i think the sanctions are just spiteful at this point and totally unnecessary. iran is a great country and could be a great ally if we'd stop f**k with them. and i, personally, prefer their form of theocracy to those wahabbist f**k in arabia.
