It really wouldn't be a fight at all for the AUT in a standard duel, since he has such a huge advantage. I see where Penkala's coming from, if you're going to do a duel at least be a man and have a fair fight. It'd be different if the advantage was small, but 3 military wonders, 1000 infra, and 400 tech is a pretty big gap for smaller nations.
The AUT's major stats:
Technology: 562.12
Infrastructure: 1,999.87
National Wonders: Foreign Air Force Base, Great Monument, Great Temple, Internet, Manhattan Project, Pentagon, Social Security System, Stock Market, Strategic Defense Initiative
Nation Strength: 12,475.202
Penkala's major stats:
Technology: 100.21
Infrastructure: 999.99
National Wonders: Manhattan Project
Nation Strength: 4,069.783
Edit: You guys aren't even in range of each other
