Unfortunately, it appears the liberals and the MSM have done an effective job at stopping the Bush Doctrine. Iran should have been taken care of long ago, but now I feel the President is too hesistant to take this one on.
After Iraq started, you can find countless quotes by the liberals about how horrible and crazy it would be to attack Iran or Syria. Their agenda has been to protect those villains from the beginning. They know that finishing the job effectively would help republicans, plus the democrats are almost all left wing Kool Aid guzzlers at this point.
