I was about to cut your message short but I rather keep it all just to be sure I dont miss out on anything.
Norlanders must have been blind and deaf as the plan was not to have Mansbridge handed over to you but to let the treaty run out and then attack MI in full force making the northern part of MI to fall into Norlands hands once again, MI suspected that and thats why they did fill Mansbridge up with Militia. The time was specified in the treaty but Norland decided to break in and by doing so the guardians of the treaty had no options then to fulfil their duty. There were no backstabbing at all as the discussion in the rulers channel revealed all that happened prior to Norlands attack on MI.
Norland had failed to honour the treaty so the guardians of the treaty acted as promised.
I know for a fact that several Norlander knew what happened outside and what was talked about outside of Norland as they were informed by Sordnaz and the former ruler of Caergoth at the time.
None of the allies told Norland to trust Minas Ithil, it was the other way around as we all told Norland to muster for war.
Minas Ithil had no new allies and BoM never became one as it was not in their interest.
There are no defence for Norlands actions at the time except that the common nobles might have been fooled by their ruler and that those who had facts was ignored, at the begining of the war BoM was dancing around in the north doing as little as possible while trying to negotiate with Norland but as that failed the war then turned even uglier and all because Norland broke the treaty.
If its true that the Norland council was unaware about the plans then we all were deceived as we were told many time to wait for the Althing to discuss things before the ruler came back to us when we made the plans to rebuild Norland into the former self.
I was not part of the Althing on those days, since my char was new and I wasn´t a lord yet, but from what I can remember, we were informed about was that MI had broken the treaty refusing to hand over the region, and not improving relations. And the guardians of the treaty weren´t going to do ANYTHING to fix that, so either we realized we were never getting Mansbridge and let it be, since MI wouldn´t handle it and the guardians wouldn´t do anything, or we attacked and performed a TO on the region.
That´s why we ended up voting for peace. I believe if there was a plan to wait for the treaty to expire and then attack we would have waited, improved our regions and army.
