An interesting observation from Ilan Goldenberg: When Ahmadenijad is planning to visit Iraq, he announces his trip well in advance much in the way that leaders normally do before visiting foreign countries. But when George Bush goes to Iraq, security concerns dictate that the visit take place in secret with no advance notice. This even though the country in question is currently under US military occupation. Or perhaps rather than "even though" we should say because.
