If your head has been spinning since Donald Trump walked into the White House Rose Garden  and declared “Liberation Day” last Wednesday, we don't blame you. And not just because it was nauseating watching the stock market or your 401(k) crash down, but because it wasn't clear what exactly we were looking at.  As our guest today, economic historian and Free Press columnist Niall Ferguson, wrote in our pages last week:  "Depending on your worldview, you probably think Trump’s tariff blitz is one of two things. Either a committed protectionist is trying to Make America Great Again by killing “globalism,” ending “forever wars,” and bringing manufacturing jobs back to the United States. Let’s call this Project Minecraft. Alternatively, an unhinged demagogue is crashing both the world economy and the liberal international order, mainly to the advantage of authoritarian regimes…But here is what is actually happening: The American empire that came into existence after the failed autarky and isolationism of the 1930s is being broken up after 80 years. Despite Trump’s imperial impulses—wanting to annex Greenland, calling for Canada to become the 51st state—he is engaged right now in a kind of wild decolonization project." Whether or not you agree with Niall’s conclusion, there’s no question that the real story here is not about the particular tariff rate for Cambodia or Taiwan; rather, it’s fundamentally about reordering America’s place in the world.  Over the past decade, there’s been an intense debate over what role America should play on the world stage, in geopolitics, in trade, and in technology. Trump has made a very clear set of decisions on that question. And that’s the case whether or not most Americans understand the consequences. So what are the consequences when the U.S. acts unilaterally to upend the global trading system? What is the outcome when the U.S. weaponizes its own economic power? What happens when the world order, as we know it, is upended? Will these actions embolden our adversaries, or weaken them? Will this ultimately make us poorer, or better off? Has the American empire reached its end? And, was this inevitable or self-inflicted?  One note: While Bari and Niall were recording this conversation, Trump announced a 90-day pause on the reciprocal tariffs. Notably, there’s no pause on the tariffs for China. In fact, it went up to 125 percent. But the point remains. And the face-off between America and China has only heated up. What does that mean? Is the twenty-first century destined to be ours, or China’s? All these questions and more with Free Press columnist Niall Ferguson.
