$600B of reserves of RF, which are frozen, is the cost of a just single major city. It's not enough to cover loses from Russian war, because Ukraine lost 2 major cities (Donetsk, Luhansk) and whole Crimea at the beginning of the war. Everything confiscated will be just a little fraction of lost value.

IMHO, RF should give Cuban and other territories, confiscated by USSR, back to Ukraine as compensation for 8 years of war and massive destruction of Ukrainian cities.
