"Few people did as much to shape the trajectory of American diplomacy and American influence in the 20th century as George Shultz. He was a gentleman of honor and ideas, dedicated to public service and respectful debate, even into his 100th year on Earth. That's why multiple Presidents, of both political parties, sought his counsel. I regret that, as President, I will not be able to benefit from his wisdom, as have so many of my predecessors."
