Below is Casey's first answer of the interview (quite a bit more follows at the link above). Bold in the original. Yes, I'm ready for the downvotes.

Doug Casey: That’s just what the US needs: another war, and this one on the border.

The people who back the use of military force in Mexico can only be described as thoughtless warmongers with no grasp of either ethics or history. If the war against organizations like the Taliban in Afghanistan was a world-class disaster, would an invasion work out better in Mexico, which has three times the population of Afghanistan, is much richer and much better organized? And they’re right on the border, which is really asking for trouble.

The solution to the drug cartel problem is to legalize all drugs. The fact is that anybody who wants drugs today can get them easily, even if they’re in high-security prisons. From a practical point of view, making drugs illegal doesn’t work. All it does is greatly increase the price of the drugs in the US and create huge profit margins to import them. Even if you destroyed every cartel in Mexico, people that want drugs will still want them. As long as drugs are illegal, their prices will remain high and new cartels will arise.

But despite the relaxation of penalties on cannabis, it’s highly unlikely drugs will be legalized. The DEA, one of the most corrupt Federal agencies, is a permanent lobby to keep them illegal. And there’s way, way too much money in keeping them illegal.

The only solution is to learn a lesson from Prohibition in the 1930s. When they illegalized alcohol in the 1920s, it created the profits that allowed the Mafia to grow. It certainly didn’t cut down the amount of drinking; it just increased the amount of crime. Similarly, the insane War on Drugs is responsible for the success of the cartels.

They say fentanyl, an important medical drug, kills 50,000 to 100,000 Americans per year. That’s mostly because its quantity and quality are uncertain, a consequence of its illegality. But the real question is ethical: Does government have a right to “protect” people against themselves? My answer is: No. If people like it, it’s their body and their business. Prohibition of alcohol—which is also quite a dangerous drug—was costly, destructive, immoral, and stupid. Fentanyl, the current bete noir of busybodies, is no different.

If drugs were as easily available as aspirins through pharmacies, users would know what they were getting, and people who want them could get them at a cheap price in known doses.

Apart from recognizing that you can’t protect people from themselves, it’s important to look at the root of why many people get lost in drugs. The answer, I believe, is that they’re trying to hide from reality and blot it out. Why is that? It’s a subject for another conversation. But the irrationality and coercion caused by State intervention in private lives are part of the answer.
