Kremlin Confirms New START Will Lapse; Moscow Says It Will Remain 'Responsible and Attentive'

The Kremlin has confirmed that the New START treaty limiting strategic nuclear arms between Russia and the United States will expire at the close of Thursday. Kremlin spokesman Dmitry Peskov said Russia proposed a voluntary one-year extension to allow time for negotiations on a successor, but that the United States never provided a formal response. Despite the treaty lapse, Moscow says it will maintain a "responsible and attentive approach" to strategic stability, guided by national interests.

Key Points

  • New START - the last bilateral nuclear arms control treaty between Russia and the United States - will expire at the end of Thursday, according to the Kremlin.
  • Russia proposed a voluntary one-year extension to allow time for negotiations on a successor treaty, but Kremlin spokesman Dmitry Peskov said the United States never provided a formal response.
  • Moscow says it will preserve a "responsible and attentive" approach to strategic stability in the field of nuclear weapons while being guided by its national interests. Sectors potentially impacted include defense and markets tied to geopolitical risk assessments.

The Kremlin announced that the New START treaty - the last remaining nuclear arms control agreement between Russia and the United States - will cease to be in force at the end of Thursday, Kremlin spokesman Dmitry Peskov said.

Speaking to reporters, Peskov confirmed the treaty's termination, saying: "Today the day will end, and it (the treaty) will cease to have any effect." His statement made clear that, in Moscow's view, the pact will no longer apply once the day concludes.

New START had placed limits on each country's missiles, launchers and strategic warheads. Peskov noted that arms control specialists had earlier expected the accord to run out at the end of Wednesday, but the Kremlin's public position identifies Thursday as its expiration point.

According to Peskov, Russia proposed a voluntary one-year extension to allow additional time for talks on a successor treaty. He said the United States did not formally reply to that offer. On the lack of a U.S. response, Peskov commented: "The agreement is coming to an end. We view this negatively and express our regret."

The spokesman added that the subject had been raised in a telephone call between Russian President Vladimir Putin and Chinese President Xi Jinping on Wednesday, indicating the issue was discussed at a high diplomatic level.

Even with the treaty no longer in effect, Peskov emphasized that Russia would uphold what he described as a measured posture on nuclear matters. He said Moscow would preserve a "responsible and attentive approach to the issue of strategic stability in the field of nuclear weapons" while acting in accordance with its national interests.

The Kremlin's comments outline Moscow's position as the New START framework ends, and confirm that Russia has publicly registered both its regret at the treaty's lapse and its stated intent to remain circumspect on strategic nuclear stability.


Key details

  • The Kremlin says New START will cease to have effect at the end of Thursday.
  • Russia proposed a voluntary one-year extension but, per Peskov, the United States never formally responded.
  • Moscow asserts it will maintain a "responsible and attentive" approach to strategic nuclear stability while guided by national interests.

Risks

  • The treaty's expiration creates uncertainty about the formal limits on missiles, launchers and strategic warheads between the two countries, a development explicitly confirmed by the Kremlin.
  • A lack of a formal U.S. response to Russia's proposal for a voluntary one-year extension leaves the timeline and framework for follow-up negotiations unclear.
  • There is limited information in the public record about any successor agreement, and the Kremlin's statement underscores Moscow's regret rather than any concrete next steps.
