I understand your points but we have tried getting him to stop many times and he has agreed but then went back to doing it. He has also made threats towards me.He even made one when seeking peace. That's something you don't say when trying to end a war on the losing side.
And this is a war on him, not his alliance. I am just pointing out that is seems like he is using the bank and his alliance mats, weather they know it or not, to full a war.
I should also add in that Pubstomper tried solving this without a war. Adama did too. Both ended in him going back on his word.
