Defense Monitor Europe and Russia

As Treaty Nears Expiry, Washington and Moscow Turn Up the Nuclear Heat

By · November 10, 2025 · 2 min read

The United States and Russia just made nuclear weapons a front-page issue again. President Donald Trump said he wants tougher “testing,” later clarifying that he meant non-explosive trials of components and launch systems.

Meanwhile, Vladimir Putin showcased advanced delivery platforms designed to slip past missile defenses. No one is talking about detonating bombs tomorrow. But the temperature is up, and the calendar matters.

Here’s the clock: the last treaty that caps U.S. and Russian strategic arsenals is due to expire in early 2026. Inspections are suspended, trust is thin, and the guardrails that kept competition predictable for decades are wobbling.

In that setting, even calibrated steps—more rigorous U.S. reliability trials, a Russian parade of new systems—carry outsized meaning. The subtext is leverage: each side wants negotiating power if talks resume, and wants to avoid looking complacent if they don’t.

Strip away the noise and the facts are stark. Russia still holds the largest total stockpile; the United States is a close second; China is growing from a smaller base.

The U.S. is deep into a multi-year modernization drive meant to keep its triad credible without breaking the global taboo on explosive testing that has held since 1992.

Supporters call it sober stewardship: verify that weapons work, keep command and control tight, and make deterrence boring—but dependable. Critics warn that any “testing” talk chips away at norms and invites an arms sprint.

Why this matters if you live in São Paulo, Zurich, or Dubai: markets price uncertainty, shipping and insurance react to geopolitical risk, and allied defense bills rise when treaties fade.

If New START vanishes without a successor, the world’s two biggest arsenals would operate without binding caps for the first time in half a century. That doesn’t make catastrophe likely; it makes mistakes easier.

The story behind the story is about rules versus improvisation. Transparent limits, verifiable numbers, and steady maintenance regimes reduce fear and cost. Grandstanding and open-ended promises inflate risk and budgets.

You don’t need to choose sides to see the practical lesson: prudence beats swagger. In nuclear policy, boring is good—and predictability is priceless.
