Trump Considers Expanding Nuclear Arms and Underground Testing

What happened: Following the expiration of a key Cold War treaty, President Trump is contemplating increasing the US nuclear arsenal and resuming underground nuclear tests. It is unclear if this signals a new arms race or an attempt to prompt fresh negotiations.

Why it matters:

  • Potential escalation in global nuclear weapons development affecting international security.
  • Impacts diplomatic relations among the US, Russia, and China, the three major nuclear powers.

MNN Take: The end of a longstanding treaty has opened a debate on nuclear policy, with the US exploring options that could influence future arms control talks and global stability.
