Vladimir Putin said on Thursday that Russia had successfully tested a potent new strategic missile and declined to rule out the possibility it could carry out weapons tests involving nuclear explosions for the first time in more than three decades.
Putin said for the first time that Moscow had successfully tested the Burevestnik, a nuclear-powered and nuclear-capable cruise missile with a potential range of many thousands of miles.
He also told an annual gathering of analysts and journalists that Russia had almost completed work on its Sarmat intercontinental ballistic missile system, another key element of its new generation of nuclear weapons.
Putin, who has repeatedly reminded the world of Russia's nuclear potential since launching his invasion of Ukraine on Feb. 24, 2022, said no one in their right mind would use nuclear weapons against Russia.
Russia has not conducted a test involving a nuclear explosion since 1990, the year before the collapse of the Soviet Union, but Putin declined to rule out the possibility it could resume such testing.
He noted that the United States had not ratified the treaty that bans nuclear tests, whereas Russia had both signed and ratified it. It would be theoretically possible for the Duma, Russia's parliament, to revoke its ratification, he said.
Military analysts say a resumption of nuclear testing by Russia, the United States or both would be profoundly destabilising at a time when tensions between the two countries are greater than at any time in the past 60 years.
But there was no need, Putin said, for Russia to rewrite its doctrine on the actual use of nuclear weapons, which says it may fire them either in response to a nuclear strike against it or in the event of a threat to the existence of the state.
Responding to a question from Russian analyst Sergei Karaganov, who has advocated changing the doctrine - and even floated the possibility of nuclear strikes against European countries - Putin said: "I simply don't see the need for this."
