If I lived in Iran, one word would keep me up at night: Libya

[bhikkhu]

18. Unlike Iran, Libya, Egypt and Tunisia were led by autocratic dictators

Lest we forget, the hated Ahmadinejad was voted out of office. And if Roujani doesn't work out, they don't have to have a revolution - they can vote him out as well.

Of course you could argue that the real power is behind the scenes (you could make the same argument here as well - our "corporate masters" and so forth), but the fact remains. I would guess that Iran is much more worried about becoming Syria, and the best antidote to that is to engage and involve one's political opposition, to be a good international citizen, and to be more responsive to the needs of the population.
