Difference being that BK’s logs weren’t hypothetical, they were Sphinx saying “Hey, we’ve planned our war, we know when we’ll hit, we know who’s hitting who, start stockpiling nukes.” Our discussions were more like “‘What if NPO attacks us? That’d be bad wouldn’t it be?’ ‘Yeah but I expect them to keep their word.’” And BK was planning to hit us, their discussions were not “What if Chaos hit us?”
You’re trying way too hard to spin discussing a hypothetical scenario that had a very real possibility of playing out (and did play out!) as being a bad thing, when it’s just common sense. We never had any plans to hit NPO offensively.
If there’s a huge alliance that you historically haven’t had good relations with and they are sitting out this huge war, have historically good relations with your opponents, and have shown hints of aggression, it would be very naive to just not make a plan on what to do if they were to hit you. I’m certain that NPO has planned what they would do if BK Sphere hit them. Or perhaps they didn’t need to because they knew BK would never hit them because they had to fight upper tier consolidation.
