Is that because of economic integration, or other reasons? Since WWII, Germany and France sat on the same side of a military alliance for more than a generation against a formidable foe (which would obviously change some attitudes), and there have been other ideological developments in those countries at well (e.g. the degree that Germans are pacifists as a reaction to Naziism).

I agree I think the main problem here is that Russia isn't nearly as dependent on Europe as Europe is on Russia.

But that said, it's also very early to conclude that Russia has plans on Europe. Especially given how Ukraine went, even if the Russian leadership fully wants to invade Europe, they surely know how that would go the moment they touch NATO. Their military will be crushed and they'll be assassinated or executed if they don't end up in prison. Europe has time to correct this imbalance. Awareness of the issue seems to be one of the hardest steps however, and coming up with solutions after that is of course quite a challenge as well. It's messy and I'm glad I don't have to be responsible for it :-)
