What's really scary is that there are those who think that overthrowing the current reglead to fairies and unicorns. It will be good for the current regime to be overthrown. But why does anyone assume that will change Iran's nuclear ambitions or attitudes towards other countries like Israel? India is the world's largest democracy. It's also a nuclear power that is in a constant state of war with Pakistan and has serious internal battles over religious differences. Democracy doesn't equal peace and goodwill and we're deluding ourselves if we think that a more democratic Iran, which is a good thing by itself, will lead to any major changes in its attitude towards the outside world.
