An honorable alliance would not be treated with these terms, I agree, but NPO has much to account for to be widely considered honorable.
A part of this declaration comes close to an apology to GATO, but it does not appear sincere, and there are many other folks who deserve a sincere apology.
Perhaps if these apologies are not forced by treaty, but instead come sincerely and regardless of any treaty, then when a treaty does come, NPO can expect terms that would be given to an honorable alliance.
