President Donald Trump is stirring up the world order—in terms of trade and security. What is he trying to accomplish? What does he really want from America’s allies? And how are they adjusting to this new reality?

Trump is operating under the banner of America First. He says the United States has long put the interests of other countries ahead of its own. From trade deals to NATO spending, he has said, “They are ripping us off.” Are they? This complaint dates back to President Harry Truman.

Trump’s ideas have led to global tariffs and calls to take over Greenland, Panama, and Canada. Immigration and border security are tighter than ever. Now, world leaders are reacting. How will all of this impact economic stability, relations with longtime allies, global trade, and security—both at home and abroad? Will Trump’s agenda solve—or trigger—the challenges that lie ahead?

Time to meet our panel: James S. Gilmore, former ambassador and former governor of Virginia, Grover Norquist, president of Americans for Tax Reform, and Marco Navarro-Génie, president of the Haultain Institute in Canada.
