Listen to the segment "Steel tariffs might ruin my bacon fudge" from the March 3, 2018 episode
A global trade war isn't "easy" to win. "Trade war" isn't even good nomenclature. "War" conveys an impression of an event with a winner and a loser. But, on net, everyone loses in a trade war. It's more like mutually-assured destruction. The President may rant and rave in capital letters about his outdated notions of what makes an economy, but trade protectionism is the helicopter parenting of economics. Moreover, with the economic damage being intentionally done via stupid tariff policies and trade restrictions, worse things may happen even faster. Federal deficits are soon to eclipse the annual GDP, and a hobbled economy produces smaller tax revenues.
