Outside of the "and they need to leave the game" line (which is being debated), I don't see any intention to do you harm (By proxy or otherwise), just that you need to change your ways because, in his opinion, they don't fly anymore (whether that is true or not is a topic for another thread) . I don't see anything malicious about saying a nation needs to evolve, especially when you include the part about Ragnarok and Polar both evolving and becoming allies.
Edit: Making it clearer
