The 2016 U.S. presidential election may have been the most divisive election in modern memory. The aftermath has left the United States in a period of “agonizing reappraisal” over America’s role in the world. Four years later, the United States appears to still be at a crossroads between Donald Trump’s vision of an “America First” foreign policy and Joe Biden’s promised restoration of a “liberal international order.” This week, host Mark Hannah is joined by Margaret Hoover and David Eisenhower, prominent descendants of two American presidents, to discuss what is at stake for foreign policy in next week’s election. Does Donald Trump represent a paradigm shift in American foreign policy? Is the restoration which Joe Biden seeks possible? They also discuss America's relationship with China, a topic which looms large in American foreign policy today. Does China’s emergence as a competitor augur a coming conflict or can we avoid a second cold war?
