Dmitry Kiselyov, a Putin mouthpiece on Russian state TV, said that a possible course of action could be a Poseidon underwater drone triggering a 'radioactive tidal wave' against the UK. ‘Then Britain would be plunged into the depths of the ocean by an underwater nuclear strike. This tidal wave would also carry high doses of radiation surging over Britain turning whatever is left of them into radioactive desert, unusable for anything.’ He also warned the UK of a Sarmat 2 weapon, which Russia said earlier this month it planned to deploy by autumn. These intercontinental ballistic missiles carry ten or more nuclear warheads and could reach Europe and the US, experts have warned. Boris Johnson recently said he did not expect further Russian military failures to push Putin into using tactical nuclear weapons in Ukraine, and Russia had room to manoeuvre and end the conflict.
