Zbigniew Brzezinski, national security adviser to Carter, dead at 89

Zbigniew Brzezinski, who was national security adviser to President Jimmy Carter in the tumultuous years of the Iran hostage crisis and the Soviet invasion of Afghanistan in the late 1970s, died on Friday. He was 89.

His death was announced on Friday by his daughter, Mika Brzezinski, a co-host of the MSNBC program “Morning Joe.”

Like his predecessor Henry A. Kissinger, Brzezinski was a foreign-born scholar (he in Poland, Mr. Kissinger in Germany) with considerable influence in global affairs, both before and long after his official tour of duty in the White House. In essays, interviews and television appearances over the decades, he cast a sharp eye on six successive administrations, including that of Donald J. Trump, whose election he did not support and whose foreign policy, he found, lacked coherence.
