the eu is run by fanatical bureaucrats. one of the hallmarks of fanatical bureaucrats is their unshakable belief that everything they do is right because they've got that green box on the spreadsheet to prove it. they had to back ukraine because they've been anti-russia for years, but their inability to move numbers around on a spreadsheet to somehow win a war without using an army is proving that they are, in fact, wrong. it's an existential crisis. admitting defeat would be like an atheist admitting god exists, or a indian using soap. it's so antithetical to their very being it might destroy them. they have no choice. fanatical devotion to retardation is their only option.
