We face a special challenge in America.

James Naughtie speaks to veteran US politician John Kerry about the state of American politics and his long career at the top of global affairs.

As well as standing for president himself as the Democratic candidate in 2004, he served as Secretary of State in the Obama administration and as Joe Biden’s climate envoy.

Secretary Kerry was at the centre of some of the most significant global crises in recent history from Iraq to Iran and Syria. He still believes one of America’s greatest foreign policy mistakes was invading Iraq in 2003 without first seeking formal approval from the US Congress.

He is forthright in his views on America today, saying he has never seen anything like what the country is living through. He describes politics as defined by greed and insensitivity, and guided by the lowest aspirations. For his Democratic party to return to power once more, he challenges them to face and address the issues the American people care about, including immigration.
