Dictators will soon get their comeuppance

Recent protests in the Arab world have already ousted two regimes (Egypt and Tunisia), brought changes to Jordan's government, and have now spread outside the Arab world. There could soon be an "Egypt effect" in the former Soviet Union but I hope it then spreads to China and North Korea because those two countries need a regime change way more than any Arab country, and maybe it will finally spread to Cuba and knock down Castro's regime (and probably bring Cuban goods like cigars back onto the American market).
