…. is the title of a National Review op-ed by Larry Kudlow, Art Laffer, and Stephen Moore (bold added):

One of the ironies of trade protectionism is that tariffs and import quotas are what we do to ourselves in times of peace and what foreign nations do to u‎s with blockades to keep imports from entering our country in times of war. Or consider that we impose sanctions on U.S. enemies such as North Korea, Russia, and Iran because we want them to feel the economic pain of being deprived of imports.

But now we are imposing sanctions on our own country, putting up tariffs supposedly to make Americans more prosperous. If ever there were a crisis of logic, this is it.

President ‎Donald Trump genuinely believes that his steel and aluminum tariffs will save thousands of blue-collar jobs. And we know from our interactions with him that he truly cares about these workers in Pennsylvania, Ohio, and other Rust Belt states. We do, too, and we don’t want factories to shut down.But even if tariffs save every one of the 140,000 or so steel jobs in America, they put at risk 5 million jobs in industries that use steel.
