We are already in Saudi Arabia.
Nope he's wrong. Iraq is the pivot point. Iran is the only Islamic state in the region that is moving towards democracy and the government of Iran is struggling to hold onto power. We will have to deal with the strong possibility of a desperate Iranian government attempting to aid the neighboring Iraq. If we install a democratic regime in Iraq, Iran will topple like a house of cards. Saudi Arabia on the other hand is ruled by a monarch who has for years walked a line between friendly realtions with the US and placating a populace that is increasingly extreme Fundamentalist and hates the west. Civil war in Saudi Arabian is also very possible.
