You being down-voted is more testament to the orientation of thinking clouding judgment here in HN. Ukraine losing the war will be a massive blow for Europe. Sibling commentator mentioned doubling of the military budget but this disregard readiness of engagement and unity[1]. Nato was the creation of the US and the US pulling out requires, probably, another entity with committed members.

>Ukraine losing the war will be a massive blow for Europe

There is no such thing. Even if Ukraine cannot recapture all of the lost territory, it's Russia who has already lost. That a country four times the population, ten times as rich has incurred a million casualties, switched to a war economy, has to throw tens of thousand of North Koreans into a war in Europe, merely to creep forward by a few meters has to be the largest humiliation to an alleged "great power" in a century.

All of this while Europe has not even remilitarized, with Ukraine becoming a major producer of military technology in its own right, the country is now largely self sufficient in terms of its drone output among other things, is one of the strongest signs of resilience of this continent.
