One of the most chilling things about this TL is this:
Whereas the disasters of the early 20th century were (largely) the result of bloody interstate conflict, the disasters that have struck the TTL late 20th century have been the result of governmental incompetence and mismanagement.
Magnus Malan, Lesser Mao, Donald Rumsfeld, Douglas Coe, and many other rulers of this period all claimed that they were building a bigger, stronger nation. They all claimed their actions were for the greater good. They all claimed they were protecting their people from outside threats. But in the end, they did more damage to their own countries than any enemy ever could, and became as bad as the people they were opposing.
Like all the colonizers out there, Malan called himself "a defender of civilization" and a "warrior against communism." But he had little problem sacrificing such petty Western things like human rights and rule of law. Even toward his own people, he had become incredibly exploitative. And as his reign dwindled, he would also destroy and contaminate the lands he claimed he was civilizing.
Lesser Mao called himself a defender of the Chinese people and the heir to his uncle's Revolution. But by the time he dropped the bomb on Kwangsi, he was no better than the Emperors or the evil European colonists. He turned China into one giant Congo Free State, working his people to death for a single cash crop, and happily exploiting the misery and poverty of the nations around him. And in the end, he plunged his people into decades of even more terror and violence.
Donald Rumsfeld called himself a defender of free enterprise and freedom. But like the commies, he was willing to imprison and torment his own allies for daring to question his ideas. Him imprisoning Goldwater is the equivalent of Stalin imprisoning Karl Marx. And his economic policies degenerated into a wicked form of state capitalism. And by the time he was overthrown, he turned America from prosperity to poverty and desolation.
Douglas Coe picked up the pieces of Rumsfeld's mess and promised good Christian Values. And like the Lesser Mao before him, he had little problem cracking the nuclear whip, building slave labor camps, and poisoning his own people when they dared to resist his lunacy.
Collectively, these men leave behind a death toll that could potentially surpass that of the previous two world wars combined. Their pride proved to be more deadly than even the genocidal madness of Adolf Hitler.
