From European perspective, Russia's latest invasion was a wake-up call that the peace isn't permanent, and diplomacy and economic power may not be sufficient to keep it.
Effectiveness of drones and advanced missiles in the war was also a wake-up call that semiconductors and batteries have a strategic military importance, and the rest of the world is quite dependent on China and Taiwan for these.
I assume that all the talk about trade deficits and unfair competition from Chinese EVs is bullshit, and the US and the EU are having an "oh shit" moment realising they're unprepared for the world where wars are fought with drones and robots.
No, I am not suggesting this. And to my knowledge neither did Russia at any point suggest this. If Russia did, kindly share. The probability that Russia will invade Europe is propaganda propagated by western media. Request you to watch the 2 videos I have linked above.
You are, in fact, either suggesting that or are entirely unaware that Ukraine had a peaceful agreement with Russia prior. The entire point of giving Ukraine official sovereignty was to reduce international pressure on Russia - everyone knew that reneging it would bring war to Russia's doorstep, it's written in black and white on the Budapest memorandum.
You can blame Russia for not knowing their worth, but they did break the treaty and there is no rational justification for doing so.
But that is what you are insinuating about Ukraine. We should not have let the Ukrainian people self determine their path and instead given them the cold shoulder and left them to Russia.
Which is itself ideological, being based on a theory of conflict. The giving up of those capabilities was a result of times of peace.
