Charles M. Kupperman

Charles M. Kupperman served as Deputy National Security Advisor under Donald Trump in 2019 and has been known for his involvement in U.S. national security policy. Recently, he has publicly criticized Trump, drawing parallels between Trump's approach to foreign policy and that of former British Prime Minister Neville Chamberlain, who is infamous for his appeasement of Adolf Hitler prior to World War II. Kupperman asserts that Trump's legacy may be defined by a similar tendency to concede in the face of aggression.
