Colin Powell became a household name because of the four stars on his Army uniform and his iconic statements about Iraq.

In the first Iraq war in 1991, he famously described what the U.S. would do to the Iraqi army that had invaded neighboring Kuwait: "We're going to cut it off, and then we're going to kill it."

Such chilling bravado — and the subsequent victory over Iraqi leader Saddam Hussein — made him one of the most formidable and admired public figures.
