muhc like how some fans say the Taurians "were play for fools" in the Jihad, we as players have the benefit of complete information, aka player knowlege, so we know that the Taurians in the Jihad, or the Star Leauge prior to the Coups are being played for fools. that is what can be the most frustrating, because we see the moving parts and where things are going. But Kerensky and Richard Cameron did not, and the rest of the Council could care less about Amaris' influence over the First Lord.
The BEST information Kerensky had was a discomfort with Amaris' influence, and a dislike of the man on a personal level. you do not disobey the lawful orders of your commander in chief because you don't like his friend.
