Sorry, I should phrase it better. It's obvious that some EU countries were involved in conflicts and not necessarily on the good side, but not as the European Union as a whole. Countries in the EU are independent, they are not like states in the USA. The EU doesn't control them. The European Union was established to unite countries economicaly and next was transformed to align with the ideals of unity and in consequence make the the world better, just listen to the anthem. The EU does not have an army, and today this is precisely one of the topics being raised. I believe it should not have one. We are too strongly misaligned internally.
I don't agree recent history shows we are close to be like Russia, China and or USA. First of all Russia. Russia is the most aggressive country with a lot of military power including nuclear arsenal. There is no freedom of speech. There is no democracy and it is ruled by an oligarchy. The mentality of people including soldiers is, I don't even know how to express it. Since the time of the Soviet Union basically the same. Rape, murder, plunder. This is not Putin's war, this is the war of most russians.
Next China, no democracy, power in hands of the Communist Party. They are sharpening their teeth on Taiwan. They are supporting Russia and North Korea. They carry out ethnic cleansing, for example they persecute Uyghurs.
USA, basically an oligarchy. It doesn't matter who is in power, Democrats or Republicans, they always send the military to keep the oil money flowing.
Even Ukraine is not flawless. There is significant corruption there. There are also lot of Nazi sympathizers(Zelenskyy included), with their red and black flags. They exalt Stepan Bandera and his crimes. Ukraine still hasn't allowed Poland to exhume those murdered in Volhynia, and they brazenly name streets after murderers. And yet, everyone is helping them against the Russian onslaught.
Or a half of a man in case of torso.
