Yahoo News' Michael Walsh on the unique relationship between Powell and Bush:

Former Secretary of State Colin Powell celebrated former President George H.W. Bush’s foreign policy legacy on Sunday, but saved the bulk of his praise for his old friend’s character and humility.

Powell got an insider’s perspective of Bush’s administration as chairman of the Joint Chiefs of Staff from 1989 until 1993. Just days after Bush’s death at the age of 94, Powell appeared on CNN’s “State of the Union” to look back on the former president’s legacy. He said one of the reasons for Bush’s foreign policy successes is that he had more experience in foreign affairs than any president in American history. Before becoming president, Bush had been a solider, envoy to China, ambassador to the United Nations, CIA director and vice president.

“What other credentials do you need to be a successful president with respect to foreign policy? So, he knew the world,” Powell said on Sunday. “He understood so many of the personalities who were working in the world at that point. And he was essentially fully prepared to be a foreign policy president. And he was a successful one, a very successful one.”

But Powell said Bush’s remarkable humility played a significant role in helping him to lead toward a “new world order” in which all of the world’s nations would work together and the Cold War’s victors wouldn’t make the same mistake that the allied nations made at the conclusion of World War I — by burdening the losers with all the blame and responsibility.

“That’s who he was. He was like that with everybody,” Powell said.
