Foreign policy after Trump, Part 2: Iran, Afghanistan, and our alliances

When he ran for president in 2016, Trump promised he would revisit America's role in NATO and the World Health Organization, as well as the Iran nuclear deal. And true to his word, he rattled the world's biggest organizations — often pulling the US from its ranks.
