Can the possible non-extension of the New START Treaty influence the strategic stability in the use of the outer space domain?

The New START Treaty, which limits the number of deployed strategic nuclear weapons, will expire in February 2021. According to the assessment of most arms control experts and, for example, the former US and Russian Foreign Ministers, the non-extension of the New Start Treaty will have a number of negative effects. What are the possibilities of the subsequent development if the last US-Russian control-arms contract New START is not extended? And what would that mean for strategic use of the universe?

The unfavorable security situation in the world in recent years is characterized, among other things, by deepening crisis of the bilateral arms-control system between the USA and Russia, built since the 1970s. The urgency of addressing this situation is underlined by the fact that both countries own about 90% of all nuclear weapons that they modernize, introduce new weapon systems into their equipment, and reduce the explosiveness of nuclear warheads and thus their declared applicability in regional conflicts. The culmination of this crisis may be the expiry of the US-Russian New START treaty which limits the number of deployed nuclear warheads and strategic carriers.

Concerns about the consequences of non-prolongation are, among others, raised by the expected disruption of space strategic stability, which could occur as a result of eventual termination of the complex verification system. In addition to notifications, the exchange of telemetry and information, on-the-spot inspections, etc., the termination would relate in particular to the contractual non-interference in the verification work carried out by National Technical Means (NTMs).
