American Empire is at its apex. We are the sole superpower, with no potential challenger for a generation. We can reach any point on the globe with our cruise missiles and smart bombs, and our culture penetrates every nook and cranny of the global village. Yet our beloved America is now reviled abroad, dictated to by arrogant judges at home, overrun by special interests, and buried beneath a mountain of debt.

Pat Buchanan is sounding the alarm. Since 9/11, more than four million illegal immigrants have crossed our borders, and there are more coming every day. Our leaders in Washington lack the political will to uphold the rule of law. The Melting Pot is broken beyond repair, and the future of our nation is at stake.

From Vietnam to the Southern Strategy, from the opening of China to the scandal of Watergate, Pat Buchanan - speechwriter and senior adviser to President Nixon - tells the untold story of Nixon's embattled White House, from its historic wins to it devastating defeats. In his inaugural address, Nixon held out a hand in friendship to Republicans and Democrats alike. But by the fall of 1969, massive demonstrations in Washington and around the country had been mounted to break his presidency.

Human history is full of the stories of peasants, subjects, and tribes. Yet the concept of the “citizen” is historically rare — and was among America’s most valued ideals for over two centuries. But without shock treatment, warns historian Victor Davis Hanson, American citizenship as we have known it may soon vanish.

After the staggering slaughter of back-to-back world wars, the West embraced the ideal of the "open society". The promise: By liberating ourselves from the old attachments to nation, clan, and religion that had fueled centuries of violence, we could build a prosperous world without borders, freed from dogmas and managed by experts. But the populism and nationalism that are upending politics in America and Europe are a sign that after three generations, the postwar consensus is breaking down.
