Putin outlines new rules for Russian use of vast nuclear arsenal

Russian President Vladimir Putin has warned that Russia could respond with nuclear weapons if it were attacked with conventional arms in the latest changes to the country’s nuclear doctrine.

In a televised meeting of Russia’s Security Council, Putin on Wednesday announced that under the planned revisions, an attack against the country by a non-nuclear power with the “participation or support of a nuclear power” would be seen as a “joint attack on the Russian Federation”.

Putin emphasised that Russia could use nuclear weapons in response to a conventional attack that posed a “critical threat to our sovereignty”, a vague formulation that leaves broad room for interpretation.

On Thursday, Kremlin spokesman Dmitry Peskov said “this should be considered a definite signal” to the West.

“This is a signal that warns these countries about the consequences if they participate in an attack on our country by various means, and not necessarily nuclear ones,” he said.

“Not for the first time, Putin is playing [a] gamble with his nuclear arsenal,” EU foreign policy spokesman Peter Stano told reporters. “We of course strongly reject these threats.”

Ukraine factor

The Russian president is the primary decision-maker on Russia’s nuclear arsenal and needs to give his final approval to the text.

The change appears to significantly lower the threshold for Russia to use atomic weapons and comes as Ukraine’s Western allies consider whether to allow Kyiv to use longer-range weapons to strike military targets deep inside Russia, and a month after Kyiv launched a surprise incursion into Russia’s Kursk region.

Putin did not refer to Ukraine directly, but said the revisions to the doctrine were necessary in view of a swiftly changing global landscape that had created new threats and risks for Russia.

Russia is making slow but incremental gains in Ukraine since it launched its full-scale invasion of the country two and a half years ago and is trying to dissuade Kyiv’s Western allies from strengthening their support.

Putin has made several implicit threats of nuclear attack since launching his war and has suspended Russian participation in the New START treaty with the United States, which limits the number of nuclear warheads each side can deploy.

Ukraine President Volodymyr Zelenskyy has urged Western powers to disregard Russia’s threats, and his chief of staff, Andriy Yermak, said Putin’s latest remarks were little more than blackmail.

“Russia no longer has any instruments to intimidate the world apart from nuclear blackmail,” Yermak said. “These instruments will not work.”

Existing doctrine

Russia’s existing nuclear doctrine, set out in a 2020 decree, says Moscow could use its nuclear arsenal in case of a nuclear attack by an enemy or a conventional attack “when the very existence of the state is in jeopardy”.

Russia’s hawks have been calling for toughening the doctrine for months, claiming the current version is too vague and leaves the impression that Moscow would not ever resort to using nuclear weapons.

Putin stressed the revised doctrine spelled out conditions for using nuclear weapons in greater detail, and that they could be used in case of a massive air attack.

“Conditions for Russia’s move to use nuclear weapons are clearly stated” in the revisions, he said.

“We will consider such a possibility when we receive reliable information about a massive launch of air and space attack assets and them crossing our state border,” Putin added, citing “strategic and tactical aircraft, cruise missiles, drones, hypersonic and other flying vehicles”.

The current version of the document states Russia would use its nuclear arsenal if “reliable information is received about the launch of ballistic missiles targeting the territory of Russia or its allies”.
