In the span of a few nanoseconds, SkyNet decides that all of humanity is a threat, and declares war by launching a large portion of the country's nuclear stockpile. Millions are slaughtered, either in the initial attack or by lingering radiation, but many still survive. The war against humanity has raged now for almost twenty years. Humanity is still recovering from the effects of the nuclear devastation wrought by SkyNet.
