to make things worse here, you cant take combined numbers and pretend such a force would cooperate and fight effectively. despite all efforts at standardisation and interoperability and flashy (small-scale) coreographed exercises, the idea nato standards exist except as lowest common denominator is a pipe dream. that was a pipe dream even at the height of cold war, let alone now after decades of neglect and other bullshit.  the idea spanish brigade would fight as well as american brigade and so on is rubbish. the mere idea spanish and italians would deploy to die in eastern europe is also fantasy.  theres few states which might get along with this (major powers and poland, baltic states, maybe romania but i doubt it), but together they wouldnt be able to match 20% of ukrainian overall combat power.  ukraine is the nexus of nato support, everyone pooled in, its basically the best equipped and largest and most organised nato land force in europe.  and while theyre holding ground, the idea they could ever defeat russians militarily is pure fantasy.  what the fuck would nato be able to do? with few materiel reserves, almost no manpower reserves, no experience, nothing. led by officers who in most armies werent promoted due to competence but by nepotism and politics, because they parroted official ideological line well.  these might be universal problems, that obviously existed in ukraine and russia, but after three years of war a lot of chaff was separated from the meat. this catharsis never happened for these armies.
