Changes may be made to the Russian nuclear doctrine in light of the Ukrainian conflict, local media reported Thursday, citing Russian Deputy Foreign Minister Sergei Ryabkov.

Ryabkov said “further clarifications” would probably be made to the doctrine to reflect the experience from the Ukrainian conflict “when the classic old interpretation of nuclear deterrence did not work properly,” RIA Novosti reported.

Russia is ready to do everything to ensure its security, and “Western provocateurs” must understand this, Ryabkov said.

He also noted, however, that everything must be done to prevent a slide into the use of nuclear weapons.
