SEOUL, South Korea — “Self-restraint” is all that is keeping the United States and South Korea from going to war with the North, the top American general in South Korea said on Wednesday. His comment came as the South’s defense minister indicated that the North’s first intercontinental ballistic missile had the potential to reach Hawaii.

The unusually blunt warning, from Gen. Vincent K. Brooks, the commander of American troops based in Seoul, came a day after North Korea said it successfully tested the Hwasong-14, its first intercontinental ballistic missile/New York Times. More here.

Question: What action should we take against North Korea?
