Jane Harman, who served nine terms as a US Democratic Congresswoman from California, explains that the Biden administration's approach is "to take the foreign out of foreign policy." Biden's foreign policy strategy starts with restoring alliances, promoting democracy, and making the world safer, prioritizing issues that connect what the US does abroad to concerns at home, says Harman. That means finding a solution to the pandemic both in the US and globally; addressing terrorism abroad and domestically; and climate, which Harman notes, "is a huge part of our security at home and security in the world. Think about it. Half the refugees in the world are climate refugees. They're not terrorism refugees."

Harman, author of the new book, "Insanity Defense: Why Our Failure to Confront Hard National Security Problems Make Us Less Safe," spoke in an interview with Ian Bremmer.
