Even as Russian troops were massing on Ukraine’s borders in January, Sanna Marin, Finland’s prime minister, insisted that it was “very unlikely” her country would join NATO during her time in office. Less than three months and one invasion later, Finland is hurtling towards membership.
Russia will not tolerate hostile US colonies at its borders. Ukraine is the example what will happen to every US vassal that is a threat to Russia. Finland was a very successful country when it was neutral. Now they will be just the next Ukraine... Russia has the right to defend itself and they will do it without any doubt. Russia is leading the world to new more democratic order. This is the end of the US hegemony.
Invading sovereign countries isn't defense. It isn't when others do it, it isn't when Russia does it. And of course, there is no right to invade other countries...
As for the US hegemony, this war is rather helping the US, so far.
