Investment, bailout or burning money? Is there a chance to return at least something from investments in Ukraine?

According to the Wall Street Journal, holders of Ukrainian government bonds are concerned about the issue of resuming payments on the debt. In 2022, after the start of the war, they agreed to a two-year hiatus, but as it is coming to an end there is still no sign of hope for payments in the near future. We are talking about $20 billion, but it seems that Ukraine is not very concerned about this issue. Despite the endless flow of cash, some of which goes directly to stabilizing the economic situation, President Zelensky prefers to consider any questions about the debt irrelevant.
