When the mutant time traveled he didn’t know Tucker tagged along. Tucker seeing that force wasn’t going to conquer the world, had a different plan. Only problem was, his younger self didn’t want to listen to him, starting a civil war in rittenhouse. A loyal agent to future Tucker, named James started the conquest of NAU. Then future Tucker tricked present Tucker onto Harold’s property where he was shot. He then took over the other half of rittenhouse and made both Romop and NAU fall under his control. Now he is exploring different ways to conquer other nations, without necessarily making another nation win out. Note that the way things will work is you would still be in charge, just as your evil rittenhouse dude. Nations do not know this, this project is just here to make all this canon.
