The Iran conundrum
Canadian journalist David Warren spells out the horns of our dilemma with Iran succinctly and clearly.

Once armed with nukes, and even without actually using them, Iran's ability to project power throughout the region - both diplomatically and through Hezbollah - is much enhanced. The mullahs' chance of surviving domestic challenges to their power will be likewise enhanced. Saddam's domestic power came from the common belief that he was armed with hideous weapons.

To sum up, the West is in no position to act boldly against the ayatollahs. But they, for their part, are now acting boldly against us.
