Averting the U.S.-Russia Warpath

Even as U.S.-Russian tensions have risen, fundamental shifts in the military-technological environment threaten to erode strategic stability between the two nations.

March-April 2018

As the United States proceeds with a program of nuclear modernization, it should also develop and deploy nonnuclear hypersonic weapons, tailored to defeat major improvements in the air-defense systems of potential U.S. adversaries. The United States should aim for a “sweet spot” for nonnuclear hypersonic weapons in terms of military effectiveness (high), cost (relatively low), potential for high-volume strikes (significant) and impact on strategic stability (low). Medium-range ballistic missiles (with and without boost-glide vehicles) and hypersonic cruise missiles, launched from heavy bombers and/or attack submarines, could fall in this sweet spot. The systems would have a low impact on strategic stability because their infrared and other signatures would be substantially different and distinguishable from those of U.S. nuclear-delivery systems (including SLBMs and nuclear-tipped cruise missiles), attacks on one nation would not require overflight of others, and these systems would either lack the range to attack deep into Russia (the case for submarine-based medium-range systems) or would be unable to do so in volume without creating a massive detectable signature (the case for bomber-based systems).

The United States should also invest in its missile-defense architecture. To start, as North Korea improves its nuclear-tipped ICBM capabilities, the United States should continue to grow its missile defenses. Second, the United States should continue to press forward with directed-energy systems for defensive purposes. Priority should be given to helping to deal with the immediate challenge of negating North Korean long-range and medium-range missiles, likely by deploying directed-energy systems on manned or unmanned aircraft. Third, the United States should forswear space-based missile defense interceptors and directed-energy systems, strongly urge Russia to do the same and pursue a bilateral agreement with Russia (and, separately, a bilateral agreement with China) to this end. Because of the massive and immediate threat that such systems would pose to American satellites and their essential support to warfighting—and potentially to early warning and secure communications satellites that are vital to the U.S. nuclear deterrent—any Russian deployment of space-based missile defense interceptors or lasers would pose an immediate and unacceptable threat.

Finally, the United States should regularize strategic-stability talks with Russia and seek to extend the New START treaty by five years. The U.S.-Russian meeting in Finland in September 2017 was an important first step toward a regular Track 1 dialogue on strategic stability issues in the coming years. The American and Russian governments should sustain these sorts of efforts. At the same time, however, in view of the volatility of U.S.-Russian relations at this time, and recognizing that circumstances may delay or derail Track 1 efforts, both parties should pursue Track 2 and Track 1.5 dialogues on strategic stability. Extending New START would serve strategic stability through its verification provisions, which provide transparency and predictability, thereby reducing the propensity of each side to rely on worst-case assessments. It would not currently be helpful to press for further reductions in force levels, as having some extra margin above the bare minimum force levels that each side thinks it needs will help buffer the impact of new military capabilities as they are deployed.

THE UNITED States and Russia have reentered a period of serious tension that shows no sign of abating. Relations between the two sides appear likely to remain tense, if not hostile—at least through the medium term—and may involve considerable turbulence. Bluntly put, serious disagreement and even outright conflict are possible. Exacerbating this geopolitical reality, emerging new military capabilities—cyber, space, missile defense, long-range strike and (cutting through all) autonomous systems—are increasing uncertainties associated with strategic stability. Unless measures are taken to cushion the consequences of these military trends, conflict may become more probable and escalation more dramatic and severe than they need to be—all in an era when both crisis and conflict are more plausible than they were just ten years ago. If adopted by the Trump administration and its successors, a fresh American approach to U.S.-Russian relations will protect American and allied interests. If the U.S. approach is also articulated clearly and is consistent over time, it may well reduce the risk of crisis or conflict arising from Russian miscalculation.
