Proof ?
If I told you that Free Republic moderators has been infiltrated by agents of the Democratic Underground, youd be hard-pressed to come up with any argument to refute that statement.
Let's just go back to 2002 and think about what Iran must have been thinking during the U.S. preparations for the invasion of Iraq. If someone had approached the Iranian government and suggested that within five years the following conditions would be in place . . .
1. Iraq's Ba'athist government overthrown
2. Saddam Hussein executed
3. A new Shi'ite-dominated government in place in Iraq
4. The U.S. utterly incapable of mounting a serious military campaign anywhere in the Middle East
5. The ruling party in the U.S. government thrown out of office
6. Iran's biggest export (oil) trading at historic high prices
7. (As a result of #6) Iran's nuclear program accelerated.
. . . I suspect nobody in Iran's government would have believed you. They couldn't have done any better if they had placed their own agents in position of power in the U.S. government.
