The administration line is this: The Middle East is a hornet’s nest for terrorists. Dealing with the situation by swatting individual hornets as they come to sting you might help improve the symptoms temporarily, but unless you get rid of the nest, you’re going to have to keep doing so forever. And in a world where weapons are getting increasingly powerful and increasingly easy to come by, this situation is bound to end in disaster.
So the administration has decided to get rid of the nest. Conditions for Arabs needs to be improved. The dictatorships have to go or reform, the Palestinian situation needs to be resolved, and the people of the middle east need to be turned into allies instead of enemies.
This is where Iraq fits in. With a crazy dictator in the middle of the problem, throwing money to Palestinian suicide bombers, firing missiles at Israel, invading his neighbors, and inciting Arabs to hatred of the west, the problem was intractable. But get rid of Saddam and replace him with a democracy, and you can win the hearts and minds of Iraqis, and remove the need for Saddam’s neighbors to build their own WMD.
Iran is another problem of the same scale as Saddam, with their heavy funding of Hezbollah and constant inciting of hatred against the west. But the U.S. is taking a very different tack with Iran, because it sees the potential for peaceful change. For example, the U.S. immediately offered large amounts of humanitarian assistance after the Earthquake, and breaking news yesterday is that the Bush administration has offered to send a delegation to Iran consisting of Elizabeth Dole and an unspecified Bush family member.
Also, the U.S. in Iraq did something very important for Iran - They disarmed MEK, which was a resistance group working against the Iranian government from within Iraq. As I understand it, the U.S. has actually worked with this group before, but now they have disarmed them and declared them a terrorist organization. This seems to me to be an overture to the Iranian government.
So that’s the ‘root cause’ argument. Get rid of the root cause, and you have a chance to actually win the war on terror. Let the Middle East fester and turn the war into a policing issue of swatting the individual terrorists, and the problem never goes away.
Seems reaasonable to me.
