Which power was that?

Germany and the USSR were carving off regions and conquering small states left and right in the lead-up to WWII, both in independent adventures and their team-up via the Molotov-Ribbentrop Pact. The Munich Agreement is pretty egregious with Hitler claiming it was the last territorial demand he had in Europe and Chamberlain coming back claiming he had achieved peace for our time. Only for it to turn out that Germany would use all the fortifications, industry, manpower and resources it had gained at the expense of its neighbor to roll over the rest of Czechoslovakia. So Germany became a much more imposing force than it had started out as because folks were content to just watch it snowball and not help Czechoslovakia defend itself.

What evidence is that?

Because, again, the logic from you chicken hawks seems only to be that Europe must support Ukraine fighting Russia, because it is obvious Russia is an enemy, based on the fact that they are fighting Ukraine.

Notice the issue there? Nowhere is there any threat to Europe listed.

wait, so rhetoric is a casus belli now?

In that case, isn’t this NAFO style crap direct aggression? They’re very loud about how they’re willing to fight to the last Ukrainian - of course, not when they’d be in danger themselves - but how it’s good that Russians are dying.

Russia has made no threat I’m aware of to attack any EU member. If you have evidence of such, present it. Otherwise, your weasel words are just that.

The rhetoric does matter when Russian politicians are threatening the EU all the time by saying they’ll nuke them, that ex. Baltic independence isn’t legal, that they’re states at war, etc. But there’s concrete action too. A Russian drone strike just hit an apartment in Romania and Medvedev is saying it won’t be the last one. They’ve set off parcel bombs in EU countries. Blown up ammunition depots. Violate their airspace, send assassins into their countries, cyberattacks, influence operations to boost separatists and groups like Brexit… and even if it weren’t doing all of that, a country that conquers smaller neighbors is plenty concerning on its own.
