The Kremlin spokesman Dmitry Peskov told CNN International on Tuesday that Russia would use nuclear weapons in Ukraine only if it faced a “threat to its existence.”
“We have an internal security theory, it’s in general, you can read in it all the reasons for using nuclear weapons,” he said. “If this is an existential threat to our country, it can be applied in our theory,” Peskov said.
CNN International journalist Christiane Amanpour asked the Kremlin spokesman if Russian President Vladimir Putin was “sure” that someone close to him would not use nuclear weapons in Ukraine.
The Russian military has been facing unexpected opposition since Ukrainian forces invaded the country on February 24.
According to the Pentagon, the Ukrainian military, which controls key urban centers, has recently been able to carry out counter-attacks, especially in the south, which has allowed land to be reclaimed.
Military experts believe the Russian military is plagued by logistics and communications problems.
