Russian Prime Minister Dmitry Medvedev has said strains between Russia and the West have pushed the world "into a new cold war".
He cited Nato chief Jens Stoltenberg's speeches and films depicting Russia starting a nuclear war.
"Sometimes I wonder if this is 2016 or 1962," Mr Medvedev said.
The Cold War was a period of ideological confrontation between the former Soviet Union and Western countries. It began after World War Two and ended with the collapse of the Soviet-led communist camp in the 1989.
The 45 years of tension were marked by espionage and proxy wars involving client states - all undertaken with the knowledge or fear of the nuclear catastrophe that actual war would bring.
The Nato alliance was established in 1949 to protect Western countries.
