Hello.
How to eliminate an unnecessary competitor? We must first form an alliance with him. Then send a huge fleet to his home planet, break the alliance and instantly deliver a crushing blow. Shouldn't the AI be suspicious of such actions? Why would its ally suddenly send its entire fleet to its home planet? For a cup of coffee? This is a terrible scam. This tactic needs to be reviewed. For example, you can permanently prohibit breaking the alliance. Alternatively, you can break the alliance, but only if your fleets are located at a sufficient distance from your home planets.
