Months after North Korea showed off its largest-ever intercontinental ballistic missile, the U.S. Air Force announced on Wednesday that it successfully tested one of its own — a move that some experts say will come off as a threat to Pyongyang.

The U.S. Air Force said that it fired off an unarmed “Minuteman III” intercontinental ballistic missile (ICBM) from one of its bases in California earlier this week. Although the test was not specifically related to North Korea, several analysts believe that the country’s leader, Kim Jong Un, will still see it in a negative light.
