In my history classes, I often would compare world politics to a high-stakes poker game between ruthless players.

Iran has been at war with the United States since the Iranian Revolution and subsequent hostage taking. Now, Iran is doing its best to insure U.S. defeat in Iraq, including taking actions that kill American soldiers. All the while the Tehran regime is working furiously on a nuclear weapons program, constructing its own ace-in-the-hole.

Meanwhile, the Democrats in Congress are trying to show Iran our cards, specifically, showing them that we do not have the military action card. The mullahs are tough players. If they know the U.S. lacks the military strike card, they are confident that theirs is the winning hand.
