> So "doubling military expenditures" for most of Europe is "going from nearly zero to slightly more than zero".
Russia's defence budget is ~50 billion dollars per year.
The combined defence budgets of all of Europe is ~200 billion dollars per year, which is four times as large as Russia's. And that's from before the Ukraine invasion. The bulk of that defence budget belongs to NATO members who already have decades of experience in working together and having a shared command structure. We outspend Russia four to one, and if all European NATO members bump their defence budgets to the 2% requirement, we're gonna outspend Russia seven to one.
Going from four times the defence budget or Russia to seven times the defence budget of Russia is nowhere near going from "nearly zero to slightly more than zero".

Oh no, a million demotivated peasants with rusty Soviet-era weapons! Whatever shall we do? Best we roll over and let Russia invade and take whatever they want!
You're also stuck in the cold war mentality that Russia is still as big and strong as the Soviet Union was, and it's just not true anymore. Europe has three times the population, four times the defence budget, and ten times the GDP of Russia. Russia has had three decades of unparalleled corruption and decay, and we're supposed to feel threatened?!?
No. Stop. Re-evaluate. Russia is no longer an existential threat to Europe.
