Spot on.

[Presidents who make big changes in government policy usually lay their plans with care. They game out what might happen next. They sweat the little things. Richard Nixon did not just decide one morning to fly to China. Ronald Reagan’s tax cuts were the better part of a decade in the making. The details of Barack Obama’s expansion of health insurance emerged from countless public debates.

President Trump prefers to shoot before aiming. Declaring that he intends to reboot America’s relations with the rest of the world, he has imposed tariffs on imports with abandon, demonstrating a disregard for the details or the collateral damage. His careless conduct of the public’s business has roiled stock and bond markets, threatened to cause a recession and damaged America’s global standing. The president’s decision-making has been so erratic that at one point this week, the administration’s top trade official was interrupted in the middle of testimony before Congress because the president had just changed the policy the official was defending.

The original version of Mr. Trump’s plan, which he paused on Wednesday, imposed tariffs on foreign nations at rates that bore no apparent connection to America’s national interests. The highest tariff rate, 50 percent, applied to Lesotho, a tiny and impoverished nation in southern Africa.

The latest version isn’t much better. Mr. Trump is imposing a 10 percent tariff on imports from most nations, along with higher rates on imports from America’s three largest trading partners: Canada, Mexico and China. The average tax on imports will rise to the highest level in more than a century, raising the prices on many consumer goods. The 145 percent maximum rate on Chinese imports is intended to isolate that nation economically, but the simultaneous tariffs on everyone else will undermine that goal. And while the stated purpose of all the tariffs is to expand American manufacturing, putting them in place immediately doesn’t give companies time to build factories. It will cause pain without any benefit.]
