Honestly, she seemed to be the only interesting bit of that terrible S3E1 episode and had some promise- until she got killed off unceremoniously.

That being said, S3 was around the time everyone noticed the wheels falling off (not just the people who thought they were getting a mystery show when it was mostly an action thing to begin with), so that probably made her worse than she could have been too...

I don't (personally) know the answer but that has to be really messy.

• The European Empires started breaking apart at different rates, with Indonesia basically breaking off from the Netherlands immediately and thus may still have been counted "officially Dutch" even though it was de facto separated for years before independence. Even if the UK managed to somehow maintain 0% growth during the war, the loss of India would still be a huge blow.

• Germany lost a lot of pre-Adolf land to other countries, obviously, but there were other notable landswaps such as Poland losing some to the USSR and gaining some from Germany.

• The population transfers (between murders, deportations, and of course WAR CASUALTIES) means many of the countries weren't really the same. Ukraine actually applies well here given that many were kidnapped from their homes, some Russians were imported into the occupied territories, etc.

So while I'd confidently guess the German economy was cut by more than 2/3 and the French Hexagon might have halved, I can't personally say for sure.
