To make this thread even more confusing I'm just gonna go ahead and agree with both sides here.
On the one hand you can't really fault MHA for wanting to get rid of this treaty. They have realised by now that eternal treaties are a capital mistake and that Grämlins are far from an ideal partner (not much debate there). On the other hand, MHA can't really complain about the flak they've been receiving here since it's pretty much the expected result of cancelling a [i]'treaty that cannot be cancelled'[/i], no matter how valid their reasons.
In the end MHA has made a mistake and has both paid for it (PR wise) and learned from it (I hope).
