Are Trump's tariffs the end of the free trade era?

For the last 80 years, America has been a leading advocate of free trade. It built (and benefited from) the rules of the global economic system. But as the Trump administration imposes record tariffs on allies and renegotiates trade agreements around the world, it’s no longer playing by the rules it created. Instead, it's becoming the most protectionist advanced industrial economy in the world. What happens when globalization's biggest backer becomes its biggest critic?

On GZERO World, CNN’s Fareed Zakaria joins Ian Bremmer to discuss President Trump’s tariffs, the rise of protectionism, and US retreat from global leadership, an ideology Zakaria calls the “beating heart” of MAGA. Big economies like China and the EU that rely on trade to maintain growth are increasingly trying to go around the US to make trade deals of their own. But America still has the largest economy in the world. President Trump's trade policies could send shockwaves through the global economic system America has spent generations building. The US has imposed high tariffs on many of its biggest trading partners, and so far, economy appears surprisingly resilient. But is this just the calm before a very big storm?

“The US was the beating heart of the free trade movement, the country that forced all the other countries in the world to open their markets,” Zakaria says, “If you shelter your best companies behind 15, 20% tariff walls, they're just not going to be as competitive.”
