For me, everything is clear. Europe and America are accustomed to considering themselves the leading countries that can very easily manipulate all other countries. But the pressure on Russia did not begin even in 2014; hatred for Russians is born deep in history. But as the Russians say: "everything that does not kill us makes us stronger" Therefore, the Russian government, feeling another negative influence, as well as a dictatorship from the West, has always understood that it is necessary to prepare for the fact that sooner or later, this abscess of hatred will breakthrough. And as an example of today's events, the Russians were right.
They are ready for all sanctions, as they probably worked out all the situations that could happen in the future. But all other countries, mistakenly taking on the role of head of the world, did not take any action, always thinking that power and strength would always be theirs. But now everyone understands that this Russia is not so weak, for which it was taken earlier.
