I’m a fan of DDG still for now. But would love to hear your final decision and the logic behind it when you decide.

So, by this logic, Post-War Japan was not a sovereign state.

How a country must operate during wartime versus peace is extremely different. And the UK in WWII also issued bonds and took debt. Were they no longer sovereign?

That part of your argument is ridiculous. Ukraine is an independent nation with its own sovereignty and territorial authority.
