Globetrotting and world affairs are nothing new to John Kerry, a five-term senator who is chairman of the Committee on Foreign Relations.His duties have taken him to conflict zones and kept him in close contact with leaders around the world.Born in 1943, Kerry came of age during the presidency of John F. Kennedy, a source of continuing inspiration.“When I was in high school, a junior, John Kennedy called my generation to service.It was the beginning of a great journey, a time to march for civil rights, for voting rights, for the environment, for women, for peace.We believed we could change the world. And you know what? We did,” Kerry said.After graduating from Yale University, Kerry fought in the Vietnam War in the late 1960s, earning five combat medals.Returning home, he condemned the conflict and what he had witnessed.His anti-war record and left-of-center politics did not hinder his political ambitions.A decade after getting a law degree, Kerry ran for the U.S. Senate in his state of Massachusetts in 1984, and won.Although often overshadowed by another Massachusetts senator,the late Edward Kennedy, Kerry distinguished himself by probing the Iran-Contra affair during the Reagan administration in the late 1980s.
