The U.S. needs independent leadership and maybe even a new political party.

Senator Chuck Hagel, the Nebraska Republican and one of the very few class acts in Washington, has a new book out, "America: Our Next Chapter." Hagel writes, "In the current impasse, an independent candidate for the presidency, or a bipartisan unity ticket... could be appealing to Americans."

Hagel, who is a Vietnam veteran, also suggests that the war in Iraq might be remembered as one of the five biggest blunders in all of history. He says that the invasion 5 years ago was "the triumph of the so-called neoconservative ideology, as well as Bush administration arrogance and incompetence."
