well Grudge, it was an ultimatum because the way I saw the situation you're already tied up way over your head, while I'm pretty safe up here and in need of expansion(like all of us), so the local balance of power seems to be grossly in my favor, but you wouldn't just freely give me the island, now would you...? hence I decided to give you a peaceful way out, and perhaps even help you with your other wars, you declined so you've just got another front to your already raging war...
I too ask you to not hold any grudges(no pun intended) I'm just analyzing my situation and trying to make the best out of it...
