"This is how it should be" has resulted in millions of deaths and generations of people living under tyranny. This is stupidity. The main target of Russia and China is not Europe, but the United States. Their aggression in their local areas is just part of their overall war against Western values such as Freedom. You do not understand the anti-Western ideology of the Communists and Tyrants who face us. It will not stop with Ukraine, and then Estonia, and then Poland.
Of course the US is under attack, but we're not going to stop those attacks by defending Ukraine. The reason we get attacked is our size and strength to tip the balance in the various European wars. Both European and Russian elites agree on that. Now they have largely succeeded in neutering American capitalism and the military, so we are out of the picture. We can barely help ourselves against the Islamists and the Chinese.
