Vladimir Putin warns West of Russia's nuclear ability for sovereign defence

Russian President Vladimir Putin has warned the West about using all available means, including nuclear weaponry to defend its sovereignty. When questioned about the risks of nuclear war over Ukraine, Mr Putin said Russia's nuclear doctrine permits the use of weapons in response to a number of threats. He says the West has repeatedly accused Russia of threatening to use nuclear but claimed the accusation was wrong and instead brought attention to America’s use of nuclear in World War Two.
