Of course, in the process they will be ignoring the interventionist sanctions that the United States and the United Nations have imposed on North Korea for decades, an indirect act of war that has targeted and killed countless North Korean citizens.

In the event of war, Trump and his national-security establishment will be speaking falsely and disingenuously. In fact, the root cause of another war in Korea will be interventionism, the philosophy of foreign policy that has held the United States in its grip for more than a century.

Notice something important about North Korea's behavior: None of it is aimed at Switzerland, notwithstanding the fact that Korea is about 1,000 miles closer to Switzerland than the United States.

Why not? Why is North Korea's attention devoted toward the United States and not toward Switzerland?

The answer lies in interventionism, the immoral and destructive foreign-policy philosophy that undergirds the United States but not Switzerland.

Notice that Switzerland has no troops stationed in Korea. The United States does — tens of thousands of troops.

Notice that Switzerland does not conduct joint military exercises with the South Korea military. The United States does, on a regular basis.

Notice that Switzerland is not committed to regime change in North Korea. The United States is.

The Swiss government minds its own business. It is committed to the principle of self-defense. If another nation-state were to attack Switzerland, the Swiss would be more than prepared to defend themselves. That's why no one, including the Nazi regime in World War II, dares to attack and invade Switzerland. The Swiss would chew them up and spit them out.
