Yes the idea for airports in Bananas and similar cities would be whipped. Slavery is fine, I was just looking for a way to get the best of both worlds.
Yes the war is basically over T+5 so the need to whip units would be over, so building the Cristo redeemer would just be a way to get us out of slavery earlier. Then we can peacefully build health buildings for all our poor unhealthy cities. We can
atone for all the whipping we have done and will have done and let the world live in peace.
If you get Uranium T+3 with the aggressive plan to take out New York, you can probably arrange max OF in Moscow to build a ICBM in Moscow that turn. And launch it anywhere T+4. And if you haven't used nukes much before come on have some fun
The GM can be born in Rheims in 2 turns, so it will move T+2 and then do the trade mission T+3 so you can still use the gold to upgrade things T+3 if you want. Yes those units upgraded T+3 wouldn't be able to attack until T+4, but you can upgrade units and then load them on boats if they are in a city or fort. So the upgraded units could attack T+4 amphibiously.
Plus once you get flight in 1 turn, you can max gold T+1 and then upgrade on a lot of units T+2 even without the GM. Yes those galleys down in the south of Indian's former lands will have trouble getting into the action but they will have 2 moves T+0, T+1, then move 2 upgrade on T+2, then get into place T+3, then attack/land units T+4. Use the gold from GM to upgrade units that you load onto those boats on T+3 as long as you upgrade them in cities where the boats are.
edit: no access to the game, but this plan means those galleys can move 3+3+2+6 on T+0,T+1, T+2, T+3 (isn't that enough?)
edit#2: with refrigeration T+1, finish T+2 even 0% slider if we are still in representaion we get +1 movement on T+3 and T+4 if needed.
