Zbigniew Brzezinski: America's grand strategist

As National Security Adviser to President Jimmy Carter, Zbigniew Brzezinski (1928-2017) guided U.S. foreign policy at a critical juncture of the Cold War.

But his impact on America's role in the world extends far beyond his years in the White House, and reverberates to this day.

His geopolitical vision, scholarly writings, frequent media appearances, and policy advice to decades of presidents from Lyndon Johnson to Barack Obama made him America's grand strategist, a mantle only Henry Kissinger could also claim.

Both men emigrated from turbulent Europe in 1938 and got their PhDs in the 1950s from Harvard, then the epitome of the Cold War university.

With its rise to global responsibilities, the United States needed professionals.
