David Brown, producer of the BBC TV’s Trump - The First 100 Days, speaks to Kurt Volker, former US ambassador to NATO, about the whirlwind start to President Trump’s second term in office.

In this conversation, Ambassador Volker, who previously served as Trump’s special envoy to Ukraine, shares his assessment of the president’s programme of change - and the extraordinary pace of reform.

He gives the inside take on Trump - from that explosive White House press conference with Ukraine’s President, Volodomyr Zelensky, to his plans for the Middle East - and sets out how Mr Trump plans to make America great again.

Ambassador Volker decodes President Trump’s head-line grabbing statements on US territorial expansion and international relations - and explains the risks of doing away with diplomatic convention.
