But tariffs only do that with foreign entities by your logic a person selling war material to the Japanese in 1944 would not be doing harm to the USA. No accusation merely the extension of your logic. By the way if anyone else has a probem with either the Cato homepage link or the link to the regression analysis study please let me know so I can have the post with the link pulled. i have no problem and Protagoras seems to be.

Pick a horse and ride it. I don't think tarrifs were used to keep people from selling war materials to Japan. And it would have had to be an EXIT tariff if so.

Tariffs should be used as taxes, not national security or other reasons. They wouldn't work well enough anyway. Different laws cover national security, rightfully so.
