No American statesman has been as revered or as reviled as Henry Kissinger. Once hailed as “Super K”—the “indispensable man” whose advice has been sought by every president from Kennedy to Obama—he has also been hounded by conspiracy theorists, scouring his every “telcon” for evidence of Machiavellian malfeasance. Yet as Niall Ferguson shows in this 2-volume biography, drawing not only on Kissinger’s hitherto closed private papers but also on documents from more than a hundred archives around the world, the idea of Kissinger as the ruthless arch-realist is based on a profound misunderstanding. The first half of Kissinger’s life is usually skimmed over as a quintessential tale of American ascent: the Jewish refugee from Hitler’s Germany who made it to the White House. But in this first of two volumes, Ferguson shows that what Kissinger achieved before his appointment as Nixon’s national security adviser was astonishing in its own right. Toiling as a teen in a New York factory, he studied indefatigably at night. He was drafted into the infantry & saw action at the Battle of the Bulge—as well as the liberation of a concentration camp—but ended his army career interrogating Nazis. It was at Harvard that Kissinger found his vocation. Having immersed himself in the philosophy of Kant & the diplomacy of Metternich, he shot to celebrity by arguing for limited nuclear war. Nelson Rockefeller hired him. Kennedy called him to Camelot. Yet Kissinger’s rise was anything but irresistible. Dogged by press gaffes & disappointed by Rocky, Kissinger seemed stuck—until a trip to Vietnam changed everything. The Idealist is the story of one of the most important strategic thinkers America has ever produced. It’s also a political Bildungsroman, explaining how “Dr Strangelove” ended up as consigliere to a politician he’d always abhorred. Like Ferguson’s classic 2-volume history of the House of Rothschild, Kissinger sheds new light on an entire era. The essential account of an extraordinary life, it recasts the Cold War world.
