Uhh... because they did everything they could with the Zuma to ensure the Zuma didn't destroy them all for something they were completely innocent of?
How else would anyone have handled it?
Like I said, from the eastern prospective. Over here it appeared that Terran and their allies were rather reluctant to meet the requests, but also took their own sweat time in trying to negotiate at all. Correct perspective? Probably not but that is how it is. Similar to how D'Hara was convinced that SA was ultra militant and ready to invade on any pretext during the era of the Dragon Queen.
