My take is different, this Russian invasion has revealed all sorts of weaknesses in NATO, complacency, low military spending, a decay and stagnation in much of our weapons and ammo production, so all these new fixes are good news.
New unity, new weapon factories, replacing old stuff with new and improved, increased military budgets, new, more conservative outlooks on military readiness, we are much improved over where we were 25 months ago.
My take is different too. NATO is a useless entity, that has never accomplished any real long-term effectiveness, and the fact that they took U.S. money for 75 years, which has been the bulk of their budget all those years, and wasted it, doesn't bode well for any so-called "change" in the future. Leopards don't change their spots. You are way too optimistic. This is an organization that was established in 1949 in the post WWII era, and it's a dinosaur that should have been made extinct years ago. It's as useless as the U.N.
