RT by @mikenov: RT by @mikenov: 🇷🇺🇪🇺🇺🇸 Russia has sent NATO a direct warning over Kaliningrad, saying it is prepared to use its “entire arsenal” – including nuclear weapons – if Russian territory is threatened. NATO says it formally responded and condemned Moscow’s “irresponsible nuclear rhetoric.” Important distinction: there is no indication here of a new nuclear deployment or change in posture.
