Amendments to the Russian deterrence policy are almost ready and will take effect “as needed”, Dmitry Peskov has said

Changes to Russia’s nuclear doctrine are almost complete and will be formalized “as needed,” Kremlin spokesman Dmitry Peskov has told TASS.

The news agency asked on Tuesday about progress made since President Vladimir Putin first announced the amendments in late September, while chairing a Russian Security Council session on the issue.

Putin said the updates were necessary due to the shifting geopolitical landscape. The reviewed doctrine will list more military threats that Russia could counter with nuclear deterrence, he explained.

One key change will be to designate aggression by a non-nuclear state backed by a nuclear one as “their joint attack on the Russian Federation,” Putin stated. Moscow may also treat a mass air attack by a foreign power as meriting a nuclear retaliation, once enemy weapons cross the Russian border, he added.

At the time, Peskov said the announcement was meant as a warning for “hotheads” in the West, who continue to escalate tensions with Russia.

The spokesman’s latest remarks came after US President Joe Biden reportedly gave Kiev permission to use US-donated long-range ATACMS missiles for strikes deep inside Russia. The purported policy change, which has been confirmed by some US allies, but not by Washington, is perceived by Moscow as a significant escalation.

Putin previously said that an attack of that kind could only be conducted with the direct involvement of the nation providing the arms. If carried out, it would mean direct war between a NATO member and Russia, and would trigger an appropriate reaction, he warned.
