Not that I know of. but I am not a diplomat, I could be wrong.
You are wrong.
Also, to people saying that we should treat the Zuma as any other realm - that is not possible. Apples and oranges. "Any other realm" would have real flaws, such as troop movement not being 100% coordinated, individual player desires, and the possibility of destruction. I would personally have been fine with Astrum and/or Morek entering the war on Kabrinskia's side - they, at least, have equal risks to take. This is simply untrue for the Zuma.
