I have a suspicion that it's the same reason European aid to Ukraine has so far been a tiny fraction of what was publicly pledged: western European military capabilities are much, much more degraded than anyone is publicly admitting. After the collapse of the USSR it was fine to just write off defense capabilities for a while and lean on the American security shield, but now after ~35 years of kicking that can down the road there's nothing useful they can do to to help against a bunch of unguided rockets getting fired from the desert, never mind a shooting war with Russia.
