Kevin Roberts, president of the Heritage Foundation, and The Economist’s Edward Carr discuss the Republican Party's shift from isolationism to internationalism and back again. They explore topics such as America's foreign policy, trade, immigration, and the party's changing stance on free trade, tariffs, and alliances, including a more hawkish line towards China. They also touch on the challenges to American power, particularly from China, and whether America can continue to uphold the world order it helped create.

Henry Kissinger was one of the most influential and controversial diplomats of the 20th century. He was National Security Advisor and Secretary of State to two American presidents. Now, with China’s growing influence and the prospect of powerful technology that could change the nature of war, his ideas on great power conflict are more relevant than ever. On the eve of his 100th birthday, The Economist spent over eight hours in conversation with Mr Kissinger. In this podcast special, we focus on three elements of the wide-ranging discussion: the role of China, AI and weak American leadership. Zanny Minton Beddoes hosts with Edward Carr. The full transcript of the conversation with Mr Kissinger is available online. For full access to print, digital and audio editions of The Economist, try a free 30-day digital subscription by going to www.economist.com/intelligenceoffer.
