Titor's description of events between 2000 and 2036 effectively describes World War III and two decades of recovery.
He claims that the seeds of this conflict will begin to be seen in 2004/2005 around the time of U.S. presidential election, 2004. Continuing Muslim/Jewish tensions are still a problem at that time but are not the cause; instead, an American civil war is brought on by increasingly intrusive police state tactics more or less resembling the massacres at Waco and Ruby Ridge. The "second civil war" sees those in the cities fighting those in rural areas (Titor fought on the rural forces, joining a "shotgun militia" when he was 13).
The civil war is effectively ended by Russia in 2015 when it commences nuclear warfare on most major US cities, eliminating the federal government and thereby securing a 'victory' for the rural forces. Most major urban areas in the world are also hit by nuclear weapons in tit-for-tat retaliation. Europe, Africa and Australia are particularly badly hit in this regard and, Titor claims, are decimated as approximately three billion people die worldwide.
