Henry Kissinger turns 100, legacy remains controversial.

Former diplomat and presidential adviser Henry Kissinger celebrates his 100th birthday, having outlasted many of his political contemporaries. Kissinger played a key role in American foreign policy during the 1960s and 1970s, including attempts to pull the U.S. out of Vietnam. He has continued to advise on global affairs, providing counsel to Republican and Democratic presidents, and maintaining an international consulting business. Kissinger has also coauthored a book about artificial intelligence and warned of potential risks associated with the technology. While some have praised his diplomatic efforts, others have accused him of prioritizing American interests over human rights and enabling repressive regimes.
