The world feels heavy lately. You see the headlines, the grainy Telegram videos of missile tests, and the endless talking heads on cable news, and you can’t help but wonder if we’re actually teetering on the edge. Honestly, asking how close are we to nuclear war isn't just a paranoid shower thought anymore. It’s a legitimate question being debated in the halls of the Pentagon and the Kremlin.
We aren't in the 1990s anymore. That era of "The End of History" and relative peace is dead. Now, we have a cocktail of aging treaties, hypersonic tech, and hot wars involving nuclear powers. It’s messy.
The Bulletin of the Atomic Scientists currently has the Doomsday Clock set at 90 seconds to midnight. That is the closest it has ever been. Even during the Cuban Missile Crisis, the clock didn't tick this far forward. But a clock is just a metaphor. The reality involves real people, real silos, and real math that most of us would rather not think about.
Why the Ukraine Conflict Changed the Math
Before 2022, nuclear talk was mostly about North Korea’s latest "Christmas gift" or Iran’s centrifuges. Then Russia crossed the border into Ukraine. Since then, Vladimir Putin has mentioned his "special weapons" more times than anyone is comfortable with. It isn't just posturing; it’s "reflexive control," a Soviet-era tactic designed to make the West hesitate.
It worked, kinda. For a while, the U.S. was hesitant to send HIMARS or Abrams tanks because of the "red lines." But as those lines were crossed without a mushroom cloud appearing, some started to think the threat was a total bluff. That’s dangerous thinking.
Rose Gottemoeller, a former Deputy Secretary General of NATO, has been vocal about this. She argues that while a strategic exchange (the big city-killers) is unlikely, the "tactical" use of a smaller nuke in a battlefield setting is a non-zero probability. A tactical nuke is still a nuke. It breaks a 80-year-old taboo. Once that seal is broken, nobody actually knows where the "off" switch is.

The China Factor and the Three-Way Race
For decades, we lived in a bipolar world. US vs. USSR. It was simple. You build a sub, I build a sub. Now? China is rapidly expanding its silos in the Yumen desert.
The Pentagon projects that China will have 1,500 warheads by 2035. This creates a "three-body problem" in physics terms. If the U.S. has to deter both Russia and China simultaneously, the old math of Mutually Assured Destruction (MAD) starts to fall apart. If we have 1,550 deployed warheads (the limit under the now-suspended New START treaty) and they each have that many, we are outnumbered two-to-one.
This brings us back to the core question: how close are we to nuclear war when the guardrails are falling off? Russia has "suspended" its participation in the New START treaty. We aren't inspecting their sites; they aren't inspecting ours. We are flying blind for the first time in nearly half a century.
Accidents, AI, and the "Flash War" Risk
Scary stuff isn't always about a madman pressing a button. It’s about a sensor glitch.
Remember Stanislav Petrov? In 1983, his computers told him five U.S. missiles were incoming. He had a gut feeling it was a mistake and stayed quiet. He was right—it was just sunlight reflecting off clouds. Today, we are integrating AI into early warning systems. AI doesn't have "gut feelings." It follows logic. If an algorithm sees a "launch" and suggests a counter-strike in seconds to "save" the retaliatory capability, a human commander might not have the time—or the guts—to disagree.

Cyberattacks are the new wild card. Imagine a hacker group, not even a state actor, spoofing a command-and-control signal. It sounds like a movie plot, but the Heritage Foundation and various defense think tanks have raised alarms about the "brittleness" of aging nuclear command systems.
The Escalation Ladder: How It Actually Starts
People think a nuclear war starts with a thousand missiles. It doesn't.
It starts with a "demonstration strike." Maybe an explosion over the Black Sea to show resolve. Or a strike on a remote military base. The goal isn't to kill everyone; it's to say, "Stop, or else."
The problem is the response. If Country A hits a base, Country B can't just do nothing, or they lose all credibility. So they hit two bases. Then Country A hits a port. Pretty soon, you've climbed the "escalation ladder" created by Herman Kahn in the 60s. There are 44 rungs on that ladder. We are currently sitting somewhere around rung 10 or 15 in certain geopolitical hotspots.
Is There Any Good News?
Surprisingly, yes.

Economic interdependence is a hell of a drug. China’s economy is deeply tied to the West. A nuclear exchange doesn't just end lives; it ends the global market permanently. There is no "winning" when your customers and your supply chains are literal ash.
Furthermore, the "Nuclear Taboo" has held for 80 years. Even in the darkest moments of the Cold War—Vietnam, Afghanistan, the 1973 Arab-Israeli War—nobody pulled the trigger. There is a deep, psychological resistance to being the "second person in history" to use these weapons.
What You Can Actually Do
It’s easy to feel helpless when discussing how close are we to nuclear war. You can't control a silo in North Dakota or a sub in the Barents Sea. But living in a state of constant "pre-traumatic stress" doesn't help anyone.
The most practical step is to advocate for "de-alerting." This is a policy where missiles are taken off hair-trigger status. Right now, both the U.S. and Russia can launch in minutes. If that window was stretched to hours or days, the risk of a war starting by accident drops to almost zero.
Actionable Steps for the Informed Citizen:
- Support Track II Diplomacy: These are unofficial talks between retired officials and academics from rival nations. They often keep lines open when official government channels fail. Organizations like the Nuclear Threat Initiative (NTI) do heavy lifting here.
- Pressure for Treaty Renewal: The New START treaty is on life support. Public interest in arms control has plummeted since the 80s, which gives politicians a free pass to ignore it. Writing to representatives about strategic stability actually matters.
- Understand Local Risk, but Don't Obsess: Organizations like NUKEMAP (created by Alex Wellerstein) allow you to see the effects of various weapons. It’s a sobering tool that turns abstract numbers into "Oh, that’s my neighborhood." Use it once to understand the gravity, then close the tab.
- Focus on Cybersecurity: The intersection of cyber warfare and nuclear command is the most likely "leak" in the dam. Supporting legislation that hardens national infrastructure is, indirectly, a move for nuclear peace.
We are closer than we’ve been in a generation. That’s the blunt truth. Between the breakdown of arms control, the rise of a third nuclear superpower in China, and the hot war in Europe, the margin for error has shrunk. However, "close" is not "inevitable." The machinery of deterrence is rusty, but it hasn't snapped yet. Staying informed without spiraling is the only way to navigate this new, weird era of history.
