Sometimes you have to go against your word in defense of your friends. I know the feeling, and it sucks.
I imagine TOP feels incredibly betrayed, and yet NpO must have as well when they found out that MK and GR wouldn't be defending them or their allies in the NpO-\m/ war. I, however, understand the feeling of anger and in the end, deciding against in for the sake of your friend, despite feeling betrayed before that.
Someone was going to get hurt here, and it unfortunately turned out to be TOP.
