This is probably the result of pressure from the US because the ongoing Jewish corruption in Ukraine has become a serious public relations liability to the Zelensky govt and the neocon war effort. Zelensky no longer needs Kolomoiskys money because he now has the US tax payers funneling vast sums of money to him via Jewish Neocons pretty much indefinitely.

Kolomoisky is so insanely corrupt and evil that even Jews are wary of him. He’s like Bernie Madoff on steroids. He and likely other Ukrainian oligarchs are loose cannons and its not exactly going to help the Neocon’s Russian regime change efforts if much of the money getting poured into ukraine winds up in the Israeli oligarchs pockets instead of being used to kill Russians, as has almost certainly been happening.
