What Nuclear Threat?
This week the Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism released a draft report claiming that the odds of an attack on a major city with WMDs has greatly increased. The report rightly claims that the biggest threat comes from biological or chemical weapons not nuclear weapons. However, the report states that a nuclear threat has increased as nuclear materials and technology has significantly spread.
At least at the moment there is not much of a threat posed by nuclear weapons. First lets begin with non-state actors. Just because there is more information available does not mean that a terrorist group can immediately create a nuclear weapon. Plutonium bombs are extremely sophisticated as the mechanism requires precise implosion (known as the implosion method). Non-state actors lack the skill and resources to create such a bomb. The second type of mechanism is called the gun-type weapon. This works by shooting one piece of material into another. This technology is far more simple but it has many limitations compared to the implosion method. The first problem is that it requires a significant amount of uranium (specifically highly enriched uranium) which would be out of reach of most non-state actors. Finally, the gun method is very accident prone, although safety concerns might not be considered a limitation by terrorist groups. It seems highly unlikely that a terrorist group or non-state actor would be able to develop a nuclear weapon on their own. The skill and resource requirements are too high.
The next possible threat is from current “unstable” nuclear powers. Pakistan is a significant problem as it is becoming a haven for terrorist organizations and extremists. However, ultimate control lies behind the military who also control Pakistan’s nuclear arsenal. As long as the military is competent, coherent, and retains control of Pakistan, Pakistan’s nuclear weapons will be safe from falling into the wrong hands. In the meantime, Pakistani leaders definitely do not want nuclear material falling into non-state actor hands, even friendly hands. North Korea is the next threat but they still lack both an effective nuclear weapon and a delivery device. Their threat lies in the potential for selling off information and technology. The international community is already at work to diffuse the threat.
There’s still the threat from Russia. When the Soviet Union broke up there was the threat that portions of the Soviet arsenal would “disappear.” While large amounts of Soviet military hardware was sold off by recently turned capitalist former Soviet officers, so far it seems the selling of hardware stopped at conventional weapons. Then during the 1990s the Russian political structure decayed and became completely ineffective. The lack of oversight and safeguards significantly limited accountability over nuclear stockpiles. However, unless some group has a nuclear weapon stashed away somewhere, this threat does not seem significant. Furthermore, Russian is now on a path to reassert itself as a global power rivaling the US. It’s going to need all the military hardware it can muster, so fire sales should decrease. Finally, Russia does not want to see more groups with nuclear weapons. It threatens their security. If they feel threatened by the United States they may think twice about deploying nuclear weapons to friendly governments (Belarus comes to mind) but they will want to keep significant control over the weapons.
Now the hypothetical situation: a nuclear Iran. Iran wants nuclear weapons as a deterrent to threats by the United States or Israel. Iran has ambitions to a regional power in the Middle East; thus, it will want hegemony on military power. The quickest way to military hegemony is by obtaining nuclear weapons. During the Cold War the United States was able to maintain a balance of power with Soviet conventional forces through its nuclear weapons program. Under these conditions it seems unlikely that Iran would give nuclear handouts to its extremist buddies since they could then present a threat to Iran itself. Iran wants nuclear weapons as a deterrent to US aggression and would only use nuclear weapons if provoked by the United States.
States want nuclear weapons to protect their national security. Most of the current nuclear powers are actively involved in nonproliferation efforts. The spread of nuclear weapons presents a threat to their hegemony on global power. Nor will they use nuclear weapons unless in the most dire situation because of the ultimate repercussions for their security and power. In international relations a state’s primary concern is its national security; thus, state actors with nuclear weapons do not pose a threat to US interests.
The areas for immediate concern are Pakistan and Russia. If Pakistan’s military were to lose control, which is possible, there would be serious problems. Policy needs to focus on keeping Pakistan stable. The second threat is Russia. Just because a Russian origin bomb has yet to surface in some terrorist group doesn’t mean that it can’t happen. The key in Russia is to focus on non-proliferation and making sure Russia has secured their nuclear material. The report places too much emphasis on a nuclear threat. The real immediate threat is from chemical and biological weapons.
However, the report is right in that globalization has allowed for the spread of nuclear material and information. Regional terrorist groups can now attract a global following and a global source of doners. Technology advancement is a double edge sword. In the future nuclear weapon technology will be further perfected which will allow a bomb to be created more cheapily and with less skill. Non-state actors may not pose a threat today, but in fifty or a hundred years small nuclear weapons could be readily available. Non-proliferation enforcement is paramount.
