Yesterday, I wrote about the decades-long obsession that the U.S. national-security establishment — i.e., the Pentagon, the CIA, and the NSA — has had with Cuba. Long ago, as part of their Cold War against the Reds, U.S. national-security state officials convinced themselves that Cuba's communist regime posed a grave threat to U.S. "national security," whatever definition is placed on that ridiculous term. Of course, they've now got President Trump on the target-Cuba bandwagon.

Not surprisingly, there are tons of Republicans, conservatives, and, no doubt, even libertarian right-wingers who are ecstatic about Trump's recent executive decree that strengthens and reinforces the brutal economic embargo that the U.S. government has had on Cuba for more than 60 years. Hope for regime change in Cuba springs eternal for these people notwithstanding more than six decades of deadly and destructive failure to achieve that goal.

What these people, many of whom call themselves "freedom advocates," fail to realize — or maybe they do and just don't care — is that the U.S. embargo against Cuba has destroyed the economic liberty of the American people. In fact, I'm willing to bet that most Americans don't realize that. While the embargo, acting in tandem with Cuba's socialist economic system, brings extreme impoverishment and maybe even death by starvation to Cubans, many Americans think that it is a neutral measure insofar as the American people are concerned.

Not so! Anyone who cheers for the embargo is, at the same time, cheering the destruction of his own liberty. That should hit home with everyone who celebrates the Fourth of July.

Many people believe that it is illegal under U.S. law to travel to Cuba. Actually, it's not. The reason is that U.S. officials never wanted to portray themselves as destroying a right that has always been considered basic, natural, and fundamental — the right of freedom of travel.

Thus, to avoid doing that, U.S. officials instead made it illegal for Americans to spend money in Cuba. So, you're free to travel there but as soon as you spend money there on anything, including food, hotel, transportation, or just a tip — you are in violation of U.S. law.

Let me qualify that. It's only Americans who spend money in Cuba without the official permission of the U.S. government who are in violation of U.S. law. If you're able to get official permission to spend money there, you're okay. Thus, it's not the actual spending of money that is considered to be a grave offense. It's doing it without official permission that is the grave offense.

What happens to an American who travels to Cuba and spends money there without official permission? Upon his return to the U.S., he is fined. The fine can be hefty. For example, one company was fined $31,000 for doing photo shoots in Cuba. Another was fined $220,000 for doing hotel bookings there.
