Your perspective is clouded and your memory is selective, the hostility may have not been quite as public but you are massively oversimplifying the situation. There were numerous failed attempts by Karma to spark the war before it actually started.
The gem in my sig is even better. I'm sure it was an accident that you offered the protection of Citadel, Superfriends and CnG to Tempest in exchange for them giving you a ridiculous cb on Valhalla. That "cb" was invented by Pete MaCavoy, a guy who has done nothing but spy and infiltrate alliances including Tempest and ODN and was bitter at Valhalla because we sniffed him out. Oh yea, that happened months before the war. Yep, there was no aggressive plotting by Sparta at all. Sparta is and will continue to be the village idiot of Karma.
