The American-led West are the threat!
Russia, after making an orderly withdrawal from the former East Germany, was promised that NATO would not advance further eastwards, which is exactly what they are doing, why is that? All they have to do is keep their word and there is no conflict.
Weak political leaders under threat at home, e.g. Biden, Macron & Boris Johnson play the old self-serving political game of first scaring the population, but try to look tough, telling them that they will save them from their peril.
