It was the four decades that General Smedley Butler spent fighting wars of aggression on behalf of the United States that led him to write "War is a Racket". At no point in the history of the United States were we "pacifists" - despite the revisionist history of those who choose to ignore our long, bloody history throughout Central and South America before we embarked on our global imperial crusade in 1917.

>There would be no Holocaust and millions of lives would be saved if people attacked nazi germany preventively in 1935 as proposed by Piłsudski.

There would have been no Holocaust and no Nazi Germany if Woodrow Wilson didn't plunge the United States into the war between crumbling European empires in 1917, and had instead kept the United States out of the war (a message he campaigned on) and forced them to come to an equitable and lasting peace on their own terms. As Ferdinand Foch (The Supreme Allied Commander during WW1) said after Versailles, "This is not a peace, it is an armistice for 20 years". Instead, our interference allowing England and France to put their boot on the throat of Germany, destroying them economically and leading directly to the rise of Hitler and the Nazis.

>If Ukraine was accepted into NATO in 2008 as Eastern European countries and USA proposed - there would be no 2014 invasion of Crimea and Donbas and 2022 invasion of whole Ukraine.

If NATO didn't insist on expanding after the fall of the Soviet Union (as promised by James Baker and others) and the United States didn't spend billions of dollars to help overthrow the democratically elected government of Ukraine in 2014, there would have been no 2014 annexation of Crimea. If the NATO-aligned regime in Ukraine upheld its obligations outlined in the Minsk 1 and Minsk 2 treaties, there would have been no invasion of Donbas or Ukraine in 2022.

>You cannot solve problems with wishful thinking.

This is very true. Nor can you solve problems with delusional thinking. Since the fall of the Soviet Union the United States and NATO have invaded and destroyed Serbia, Iraq, Libya, Afghanistan and Syria. We have been bombing countries around the world from Pakistan to Somalia - bombings which continue with little fanfare and practically no attention from the media. The rest of the world (everyone outside of the US, EU and Australia/New Zealand) are well aware of our complete lack of moral and legal authority due to our long and ongoing history of worldwide aggression. The incredibly hypocrisy of pointing the finger at Russia's invasion of Ukraine while our troops right now, today, illegally occupy Syria is only lost on those who are thoroughly propagandized and/or entirely ignorant of the situation.

>Pacifism only works if both sides believe in it.

The same goes for international law and a "rules based international system". It doesn't work when the unwritten rules don't apply to us, but apply to every country that we consider hostile. The US Congress passed a bill authorizing the invasion of the Hague if any US citizen was ever indicted for war crimes! At the end of the day we can either strive for a peaceful world where every country is held to the same standards for their behavior, or we can have the world we live in where might makes right - we can't have it both ways.
