This bill puts the brakes on nuclear weapons testing by requiring Congress to approve any explosive nuclear tests before the United States can conduct them. Right now, the President can order nuclear tests without asking Congress first. This bill changes that.

Here's how it would work: If the President wants to test a nuclear weapon, they have to notify Congress at least six months in advance and explain why. There are only two situations where testing could happen—either another country tested a nuclear weapon first, or there's a genuine technical reason (like scientists need to verify that an existing weapon still works safely). For tests triggered by another country's test, Congress would need to pass a special approval vote requiring two-thirds of the Senate to agree. For tests based on technical needs, there's a faster approval process, but Congress still has to vote yes. The President would have to provide detailed information about what they want to test, why they need to do it, what other options they considered, and how much it will cost. Congress then has 120 days to debate and vote on whether to allow it.

Basically, this bill takes the power to conduct nuclear tests away from the President alone and gives it to Congress. It's designed to make sure that any decision to resume nuclear testing—something the U.S. hasn't done since 1992—gets serious scrutiny and approval from elected representatives, not just the executive branch.
