From tariff wars to torn-up trade agreements, Michael Beeman explores America's recent and dramatic turn away from support for freer, rules-based trade to instead go its own new way. Focusing on America's trade engagements in the Asia-Pacific, he contrasts the trade policy choices made by America's leaders over several generations with those of today–decisions that are now undermining the trading system America created and triggering new tensions between America and its trading partners, allies and adversaries alike. With keen insight as a former senior U.S. trade official, Beeman argues that America's exceptionally deep political divisions are driving its policy reversals, giving rise to a new trade policy characterized by zero-sum beliefs about the kind of trade America wants with the world and about new rules for trade that it wants for itself. With enormous implications for the future of regional and global trade, this timely analysis unravels the implications of America's seismic shift in approach for the future of the rules-based trading order and America's role in it. Walking Out is essential reading for anyone interested in the domestic and international political economy of trade, international relations, and the future of America's role in the global economy.
