I like to think this is true, but how many French soldiers coming home in body bags defending Lithuania will it take before they say enough? Are they going to just resort to nuclear weapons against Russia immediately? I don't think the nuclear umbrella is the trump card that it you might be portraying it to be. It's really difficult to say who would use those and when. There are some obvious cases, but there are also some not so obvious ones.
But nukes aren't enough. You're not winning the Ukraine war with your nuclear umbrella for example - that's being won on the ground with Ukrainian blood.

Combined command of a military like this is incredibly difficult, and while I'd certainly agree that some specific militaries are quite capable of [1], I think the political and organizational system in Europe really poses a challenge. But even so those militaries lack power projection capabilities and lack in some other key areas.
[1] In order probably Ukraine -> UK -> France -> Poland and then nobody else registers. Ignoring Russia because they're not really European IMO.
> Sure, it's not US level of spending... which is probably a good thing given the US basically cut education and healthcare for a few generations for that.
Nah, we actually have money to easily afford both we just have a bunch of morons in charge (Democrats and Republicans) who, particular to healthcare, have gotten us the worst of both worlds. Education we're #1 there's no question about that.
