The impeachment inquiry has exposed some of the ways in which the US diplomatic corps feels undermined and undervalued by the Trump administration. We visit two US universities training a future generation of US diplomats to find out whether students there are reconsidering their career choice. Also, Samantha Power reflects on some of the toughest decisions she had to make while US Ambassador to the UN; we visit the Museum of the Palestinian People that is just blocks away from the White House; the rise and fall of Richard Holbrooke, a statesman known for his diplomatic breakthroughs and outsized ego; and beatboxers on a musical mission to bring the world together.
