NATO criticized Putin for what it called his “dangerous and irresponsible” nuclear rhetoric.

Afghan Voice Agency(AVA)_Monitoring, Putin announced the move on Saturday and likened it to the US stationing its weapons in Europe, while insisting that Russia would not violate its nuclear non-proliferation promises.

Although the move was not unexpected, it is one of Russia’s most pronounced nuclear signals since the beginning of its invasion of Ukraine 13 months ago, and Ukraine called for a meeting of the UN Security Council in response.

While Washington, the world’s other nuclear superpower, played down concerns about Putin’s announcement, NATO said the Russian president’s non-proliferation pledge and his description of US weapons deployment overseas were way off the mark.

“Russia’s reference to NATO’s nuclear sharing is totally misleading. NATO allies act with full respect of their international commitments,” a NATO spokesperson said in emailed comments to Reuters on Sunday.

“Russia has consistently broken its arms control commitments, most recently suspending its participation in the New START Treaty,” the unnamed spokesperson said.

New START caps the number of strategic nuclear warheads that the United States and Russia can deploy, and the deployment of land and submarine-based missiles and bombers to deliver them.

A top security adviser to Ukrainian President Volodymyr Zelenskiy, Oleksiy Danilov, said Russia’s plan would also destabilize Belarus, which he said had been taken “hostage” by Moscow.

Experts said Russia’s move was significant since it had until now been proud that unlike the United States, it did not deploy nuclear weapons outside its borders. It may be the first time since the mid-1990s that it has done so, Reuters reported.

Another senior Zelenskiy adviser on Sunday scoffed at Putin’s plan, saying the Russian leader is “too predictable”.

“Making a statement about tactical nuclear weapons in Belarus, he admits that he is afraid of losing and all he can do is scare with tactics,” Mykhailo Podolyak wrote on Twitter.

Washington appeared to see no change in the potential for Moscow to use nuclear weapons in the war in Ukraine, and it and NATO said the news would not affect their own nuclear position.

“We have not seen any changes in Russia’s nuclear posture that would lead us to adjust our own,” the NATO spokesperson wrote.
