Sadly most of the great maritime powers have signed onto the 1856 Declaration of Paris where they agreed to give up privateering as a weapon of war. The United States has not signed on, but has also not issued a letter of marque since that period. During the civil war, the confederates experimented briefly with privateering, but the Union declared that it would not.
In 2025, The Cartel Marque and Reprisal Authorization Act of 2025 was introduced in Congress. This bill would authorize privateering against “cartels” (apparently any cartel, like OPEC or the American Medical Association).
When this country was founded, tariff revenue was enough to fund the entire federal government. Those days are long gone, and they’re not coming back.
Nowadays, there are basically two reasons to play the tariff game. 1. Extract tariff concessions from your trading partners, and 2. Encourage domestic production. The problem is, if you’re going for #1, you have to be willing to drop your tariffs at the drop off a hat to make a deal. If you’re playing #2, the people that build factories and whatnot want assurances that the tariff supports will be in place for years and years.
So you can see that there’s an inherent trade-off between #1 and #2. To some extent, you cannot serve both masters. But Trump has been playing both strategies at the same time without a care in the world. There are… consequences… to doing that, which I am sure we will all get to experience.
Edit: okay, okay. This Bolsonaro thing is a brand new strategy #3 which I’m calling… Oh geez… I gotta go buy some more beer.
