The Post-American World Economy
Globalization in the Trump Era
By Adam S. Posen

In the aftermath of World War II, the United States set about building a global,
rules-based economic order. At the heart of that order, it put the liberal
values of free trade and the rule of law. Over the next seven decades, the order,
backed by U.S. power and bolstered by its growing legitimacy among other
countries, prevented most economic disputes from escalating into mutually
destructive trade wars, let alone military conflict. That allowed even the
smallest and poorest countries to develop their social and economic potential
without having to worry about predation by stronger neighbors. By taking much of
the fear out of the global economy, the U.S.-led order allowed market decisions
to be driven by business, not bullying.

Today, that order is under threat. U.S. President Donald Trump has rejected the
idea that the world’s economies all benefit when they play by the rules.

Instead, he has decided that putting “America first” means withdrawing from
supposedly bad deals, on which he believes the system is based. So far, Trump
has failed to follow through on his most destructive ideas. But the damage has
already begun to show. His administration has hobbled the World Trade Organization,
encouraged China and other autocratic regimes to lean on their smaller neighbors
for economic loyalty, undercut agreements on tax evasion and climate change, and
pushed even major U.S. allies to negotiate free-trade and cross-border investment
deals without the United States.
