Russia's current strategic nuclear force will become obsolete shortly after the turn of the century. Strategic modernization is therefore essential if Russia is to remain a nuclear power on a par with the US. But modernization will be extremely difficult because of the country's economic and political turmoil. Russia can probably maintain slightly more than 4,000 strategic nuclear warheads under the Strategic Arms Reduction Talks (START) I Treaty - roughly half of what the United States could, in theory, deploy. Under START II, Russia's strategic force will likely contain between 1,800 and 2,500 warheads, compared to 3,500 for the US. Hence, the easiest - perhaps the only - way for Russia to recover rough parity with the United States would be through a START III Treaty that limits both sides to 2,000-2,500 warheads.
