The Case Against a Ukrainian Nuclear Deterrent

THE RISKS OF PROLIFERATION

The case for Ukrainian acquisition of nuclear weapons rests fundamentally on two key arguments: first, Ukrainian nuclear weapons will promote peace and stability in a region that might otherwise be prone to conflict; and second, nuclear weapons will enhance Ukrainian security, providing an ultimate security guarantee for a state fearful that its sovereignty might otherwise be jeopardized by its enormous and potentially menacing neighbor to the east-Russia.

These are not trivial or easily dismissable arguments. They suggest that Ukrainian acquisition of nuclear weapons would produce desirable and beneficial security consequences for both Ukraine and the West. At first glance, they appear to provide a convincing rationale for Ukrainian nuclear weapons.

Nevertheless, Ukraine should not become a nuclear power. Its own interests and those of the West will best be served if Kiev fulfills its oft-made pledges to join the Nonproliferation Treaty (npt) as a nonnuclear weapon state. The benefits provided by nuclear weapons are less certain and more conditional than the proponents of nuclear proliferation believe. When the costs and complications associated with nuclear acquisition are taken into account, the case for Ukrainian nuclear weapons is not compelling.

DO NUCLEAR WEAPONS CAUSE PEACE?

The case for nuclear proliferation rests on the pacific effects of nuclear weapons. As Kenneth Waltz asserts in the most famous advocacy of proliferation, nuclear spread "will promote peace and reinforce international stability." Because nuclear weapons greatly in- crease the costs and risks of war, they induce caution in the behavior of states and substantially reduce the likelihood of miscalculation. Wars between nuclear-armed states become simply too dangerous to fight. The force of this argument is greatly strengthened by the experience of the Cold War, in which the two bitterly opposed protagonists avoided war for nearly half a century despite numerous crises and provocations.
