Iran exports about 2.2 million barrels a day.

It is a natural goal of Iran to try and expel the Fifth Fleet from Bahrain.

In Iran, there is no freedom of the press, no freedom of speech, no independent judiciary, no free elections. There is no freedom of religion - not even for Shiites, who are forced by Iran's theocracy to adhere to one narrow set of official rules.

On the human rights side, administration policy has been marked by indifference. When the people of Iran flooded the streets to protest the theft of their presidential election in June 2009, President Obama was silent for 11 days.

In Arab capitals, the failure of the United States to stop Iran's nuclear program is understood as American weakness in the struggle for dominance in the Middle East, making additional cooperation from Arab leaders on Israeli-Palestinian issues even less likely.

The ultimate goal is to change Syria's behaviour on a variety of issues - on its interference in Lebanese internal affairs, on its support for Palestinian terrorist groups that oppose the Palestinian Authority, on, most importantly, acting as a land bridge between Iran and Hezbollah, where Hezbollah gets all its arms.
