Compare Iran to a swarm of killer bee's. Leave them alone and we don't get stung. Mess with there hive and most likely you will be attacked.

Iran is not a dumb country. They know damn well that if they nuke Israel or have any part in it that they too would be seeing a mushroom cloud over there nation. What good is it to wipe out your enemy completely if your not gonna be around for the victory? Iran's threats are just empty words, set on gaining support in an area of the world that has felt suppressed for a long time at the hands of foreign powers.

In China, most of the citizens there know absolutely nothing about what happened in Tiananmen Square due to censorship.
