"European Union leaders on Thursday stopped short of endorsing a plan to use frozen Russian assets to fund a giant loan to Kyiv, over concerns raised by Belgium"
It wasn't just Belgium is was everyone who understood the complexities of banking
It would be a literal economic time bomb, bc when the loan fails to be paid back & the money is officially confiscated the impact on EU's banking system would be vastly more expensive than if they had just given them money from their own coffers
