Cynic, I'm not going to defend SK's actions and the plan to attack Rose back then, because I disagreed with it entirely as an SK member then. I will say that there is a huge difference though - not only because it wasn't against a treaties partner, but primarily because it didn't happen. It was a plan in early stages that was shot down by nearly every SK member who saw it - I saw about four people in the alliance in support of it as a whole, and the rest thought it was a move with no honor and said no. Probably the biggest opposers were myself and Aisha Greyjoy, our head of military at the time who almost definitely would have kept that plan from ever happening.
I don't think it's a good thing that it was planned, I admit that. It was the primary reason I left to make my own alliance. But right now we're comparing an attack on a known enemy that was still unlikely to happen, to a direct attack on a treatied ally. There's a vast difference and I don't think DEIC should be viewed as in the right for doing this. Hell, I don't even think they should have been viewed as in the right if SK had done their shitty plan and SK had been doing it against an ally (both of which weren't true), because it's shit regardless of who does it.
