Donald RumsfeldIf I look at the really important questions in [Middle East] region, I see Iran, where there is a strong desire for a freer society and where people are repressed by a small group of ayatollahs.

These two countries fund Hezbollah and other terrorist organizations and are hurting our efforts in Afghanistan and have been extremely harmful in Iraq. Then I also see large, important countries such as Egypt and Saudi Arabia.
