The world seems to be so accustomed to casual mentions of the words nuclear strike, nuclear bombs, ballistic missiles etc that it seems to have almost forgotten that when the last time nuclear bombs were actually used in war, two cities in Japan were flattened in a matter of seconds.
These 'experts' have chosen to conveniently ignore that major NATO countries have continued to purchase billions of dollars worth of Russian oil and gas while using heavy words to denounce the Russian military operation in Ukraine, and pumping weapons into the war, basically paying both sides to fight.
While big sanctions and big statements of condemnation were announced by leaders in Europe and USA against Russia, they have made sure that Russian oil and gas continues to flow into their countries.
