CRS Reports Golden Dome Missile Defense Could Destabilize Nuclear Deterrence and Fuel Arms Competition

BLUFGolden Dome's congressional design choices will shape whether Russia and China accelerate countermeasure development or engage in arms control, but no observable force adjustments or diplomatic linkages have yet emerged to clarify which path either rival is taking.

The Congressional Research Service issued an Insight by Anya Fink on November 4 examining strategic stability considerations for Congress as it oversees and funds Golden Dome, the Trump Administration's proposed "next-generation missile defense shield" against nuclear and conventional attacks 1. USNI News republished the report on November 11, and Inside Defense carried it on November 10 23. CRS states that Russian officials describe U.S. missile defenses as an open-ended effort to undermine Russian nuclear retaliation, and that Russia and the PRC said so jointly in a May 2025 statement about Golden Dome 1. The Insight lists three questions for Congress: implications for U.S. deterrence strategy amid two nuclear peers, the timeline of Russian and PRC responses, and Golden Dome's relationship to arms control, noting President Trump has expressed interest in arms control talks with both countries 1.

Analysis
Golden Dome's effect on strategic stability remains an open congressional oversight question, not a settled finding, because the CRS Insight frames issues without assessing outcomes. Congress controls the outcome: authorization and appropriations language can make the program limited or expansive, with budget tradeoffs against other defense priorities. Russia and the PRC already describe Golden Dome as aimed at their retaliatory capability, so force adjustments, countermeasure work, or doctrinal shifts would be the first observable signals. The document offers no timeline for those responses and no sign that Washington has tied Golden Dome to arms control talks. Confidence is low: the assessment rests on one CRS document, USNI News and Inside Defense only repeat it, and there is no independent reporting on Moscow's or Beijing's reactions and no observed force changes. The Insight may also be routine framing of a recurring debate, since Russian and PRC objections to missile defense long predate Golden Dome.
