The country is officially dead. They will never be able to even remotely pay that in its entirety.
It is clear that Ukraine has no future without Russia. This enormous and unpayable debt is just one of the many reasons why. The good news is that if (or rather when) Russia wins they won't need to pay it. Whether Russia takes it all or just installs a friendly government in Kiev, the debt will be defaulted on either way. The obligations to the West that this current puppet regime entered into will be denounced as illegitimate as the regime itself was illegitimate.
If it was such a moral imperative to defend Ukraine, then why is there a price tag at all?
Not a problem: once they achieve their maximalist goals, they can auction off the regained territories to foreigners to pay for the cost of achieving their maximalist goals.

The damage from auctioning all their state owned enterprises in the middle of a war to please these ghouls will surely total to more than that.
I once counted to 1000 😎 in 2nd grade...nowadays I could probably make it to 20, if I used both hands and feet.
