For several months and years, the West's preoccupation with nuclear ambitions in developing nations, especially the Middle East, has been front page news. Tensions with North Korea are ongoing, the attack on Iraq was in part driven by fears of a nuclear program, Iran is rattling its potential nuclear sword, and now Egypt is talking about a "peaceful" nuclear energy project. Many now worry: "Are we heading into World War III?"
No. We are very, very far away from the threat of nuclear attack and not even close to the amount of tension during the Cold War. In fact, I believe there are Five Reasons that We Should Stop Worrying About Iranian (and other) Nuclear Programs:
1. Been There, Not Done That. I am only 34 years old, but I remember the Cold War clearly. When we grew up, the fear was of thousands of missiles raining down on every city and suburb in America. The world would literally end for all life. Meanwhile, the risks then seemed as high or higher than now. In the USSR, we faced: (1) a large, organized power that really was invading other countries (e.g. Afghanistan); (2) a radical belief system that felt our way of life was destined for overthrow (communism); and (3) a government that supplied resources and placed nuclear missiles throughout unstable third-world regimes (e.g. Cuba). But we survived with zero launches because the threat of mutual destruction ("deterrence") works.
2. We Should Leave Them Alone Anyway. Countries do not sign up for the extreme financial and political costs of a nuclear program because they want to attack others or support their egos. Nuclear weapons are fundamentally a defensive weapon, and when your neighbor has one your ability to defend decreases sharply. China developed a bomb because Russia had one, India because of China, and Pakistan because of India. The U.S. invasion of Iraq (no nukes) versus negotiation with North Korea (has nukes) is a clear sign to nations like Iran. At the end of the day, we should leave nations like Iraq, Iran and North Korea alone. Seeding democracy is a doubtful cause for attack, and if Iran or North Korea is not actively fighting others then we should leave them to their lunacy.
3. It Will Take a Long Time. It is not easy to develop a nuclear bomb and can take decades to do so even if the oil money is flowing freely and helpful scientists are imported from Russia. Over time, the interest in nukes may wane, oil prices might fall, or other forms of payoffs from rich nations can delay final development indefinitely.
4. Deterrence Works, Even on Nut Jobs. No one with money and power wants to die - period. The kids blowing themselves up at security checks in Iraq or Israel are the poor and powerless who are looking for a cause to join and ticket to fame. Kim Jong-il is having too much fun enjoying the fruits of leadership to risk life and limb by launching a foolish attack. Any leader with nuclear weapons knows that his use of the bomb would unleash a hurricane of much more effective missiles from the United States. Again, they are looking for defense of their power and possessions rather than truly sponsoring a holy war.
5. We Are Ignoring Bigger Threats. At the end of the day, the focus on highly exotic nuclear weapons takes our focus away from threats that are closer to reality. The attacks on 9/11 employed the technology of box cutters. Liquid-based explosives have been around since the 49ers were mining gold instead of playing football. Terrorists succeed by, well, building up fear or terror that any one of us really might die. They would rather us fear an "attack in our supermarket" than a massive, single bomb smuggled into a city. We would be better off protecting ourselves through good, old fashioned spying on suspected organizations and individuals, rather than planning stealth attacks against Iranian reactors.
Conclusion: I am not in favor of actively allowing radical nations to develop nuclear arms, and I think the world should be highly engaged in dissuading new programs and much as possible, including moderate threats and payoffs. However any attack on a country because they may be starting a program will only cost us enormous lives and expense - and further stir the hatred and fear of U.S. attack that causes governments to pursue nukes in the first place.
