You're joking, right? They said they had a few MILLION techs stationed here. Very balanced. If they think that they can get away with unfairness such as this and completely shutting down wars, then their kingdom should be stopped. Outside of RP, that is.
That could just be propaganda too, and what they actually have is far less in numbers.
You never actually struck any of their territories, so what if they mention is true or not?
The Lemons never made their motto "We are 100% honest Lemonade"
The best tactic is propaganda, what you were using before to power through and scare the other kingdoms with your "CoughcoughAnti-AI EMPcough".
You basically got schooled at your own game...
