Iran - Threat of Nuclear Capability

I attended the first half of the "National Jewish Advocacy Day on Iran" this morning in DC. We had briefings from Congressional leadership, from the Administration, and from some of the leaders and experts in the Jewish community. The central theme, which has also appeared in the news, was the frightening threat which a nuclear capable Iran would represent to Israel, to the Middle East, to the US and to the World.
As we think about the regime in Iran we know a country that sponsors terrorism (Hezbollah), that denies human rights (treatment of its own citizens), and that promulgates the worst vitriolic anti-Semitic statements (denying the Holocaust and openly articulating the destruction of Israel). To imagine such a state possessing nuclear weapons is a clear and present danger. Even if these weapons were never used - the mere capability would change the dynamics of the the Persian Gulf and the world. More frightening, on some level, is the truth, as we have learned from history, that genocidal ideas are too often implemented.
The administration has been trying to engage the Iranians without success. There are bills in process in both houses of Congress to increase sanctions in conjunction with the international community. Perhaps a stick or a carrot can change their path. We know that the clock is ticking - we need to support our government together with other countries in doing the negotiations and the pressure [and whatever is necessary] to prevent Iran's possession of nuclear bombs.
