Donald J. Trump has acted appropriately with regard to North Korea. Instead of blustering about delivering “fire and fury” to the Marxist regime, he has returned North Korea to the list of nations that sponsor terrorism.

The president has made the correct call.

He is seeking to isolate North Korean dictator Kim Jong Un in his effort to build a nuclear weapons arsenal. The aim, according to Trump, is to impose the strictest economic sanctions possible on the rogue nation. It’s also meant to pressure China, North Korea’s chief trading partner, into following suit.

I don’t know about you, but I believe this approach holds far greater potential than threats of military strikes.

The designation — which reverses a decision made by President George W. Bush in 2008 — puts North Korea on a short list of state-sponsored-terrorist nations; the others are Sudan, Iran and Syria.

Secretary of State Rex Tillerson doubts the designation will have much practical effect, given that the United States already has imposed heavy sanctions on North Korea. But he is talking openly about his “hope for diplomacy” in the effort to persuade North Korea to stand down in its effort to build a nuclear arsenal.

The great Winston Churchill once told us it was better to “jaw, jaw, jaw than to war, war, war.”

The late British prime minister’s wisdom ought to apply to the present-day crisis on the Korean Peninsula.
