For as long as North Korea couldn't strike the United States with nuclear weapons, U.S. allies Japan and South Korea felt assured that the promise of an overwhelming American military response would deter the communist country from launching attacks.
Pyongyang's emerging capabilities are upsetting all calculations. The North this weekend exploded its strongest-ever nuclear weapon and in July tested a pair of intercontinental ballistic missiles that might soon be able to threaten the entire American mainland.
The North's technological progress is adding to insecurities compounded by President Trump's sometimes lukewarm support for defending U.S. allies under his "America first" agenda.
