Russian Security Council Deputy Chairman Dmitry Medvedev warned on Tuesday that nuclear disarmament is impossible for the foreseeable future due to the global security environment.

"The situation is such that even with a complete cessation of the conflict around the so-called 'Ukraine,' nuclear disarmament in the coming decades is impossible," he said in a post on Telegram.

Medvedev blamed the United States and its allies for escalating tensions, accusing them of waging an undeclared war against Russia through sweeping sanctions and the deployment of weapons and military personnel.
