Russian state media has urged Vladimir Putin to use his underwater nuclear missile to wipe Britain off the map with a 1,000ft-high radioactive tsunami if NATO troops put boots on the ground in Ukraine.
Retired Russian general Yevgeny Buzhinsky called for attacks on Britain with a Poseidon underwater missile that he said would trigger a 1,000ft radioactive tidal wave.
Lt-Gen Buzhinsky, chairman of the Russian Centre for Policy Research, said Britain 'will definitely not exist' if Russia unleashed the wrath of the nuclear missile.
