Perhaps you can trust yourself not to fire an ICBM in the direction of an adversary. (I once launched a tactical nuke from a submarine—I was just curious.) But can you honestly trust the artificial intelligence to do the same? The answer is no. In Lycerius's world, three main powers exist: The Americans, the Vikings, and the Celts (which he plays). And they've been in a constant struggle for the last 1,700 years. "Every time a cease fire is signed," he writes, "the Vikings will surprise attack me or the Americans the very next turn, often with nuclear weapons. Even when the U.N forces a peace treaty." Unbelievable! The problem for Lycerius is that he should have never allowed the other powers to have access to nuclear material.
