Putin Plans to Find Out If NATO Actually Works

For three years, the comfortable assumption in Washington and Brussels was that Vladimir Putin would not dare test NATO while his army was bleeding in Ukraine. That assumption is now officially dead.

New US intelligence assessments, first reported by the Wall Street Journal on August 6 and confirmed across multiple outlets, conclude that Putin is likely to challenge the alliance's collective defense commitment — possibly as early as this autumn, almost certainly before 2029. The scenarios under active assessment range from large-scale cyberattacks and covert sabotage operations to what officials described as a limited land incursion into a NATO member state.

A land incursion. Into a country backed by the defence guarantees of 32 nations, including the United States. That is not a hypothetical. That is a planning scenario the US intelligence community is now treating as credible.

Why the Intelligence Baseline Flipped

Until this year, the prevailing assessment was straightforward: Russia was too consumed by its war in Ukraine to open a second front against a nuclear-armed alliance. That logic held through 2023 and 2024, when Russian forces were absorbing unsustainable casualties and burning through Soviet-era equipment stockpiles faster than industry could replace them.

The calculus has shifted. Russia's defence spending has passed 6% of GDP. Its artillery and missile production, while still dependent on North Korean and Iranian inputs, has stabilised. And the Kremlin appears to have reached a conclusion that a limited NATO operation does not require winning a second war — it requires winning a single political moment. The goal, according to US intelligence, is not to conquer territory. It is to fracture the 77-year-old alliance by forcing Washington into a choice it may not be prepared to make.

"It has always been a goal to challenge the credibility of NATO and to separate the United States from its allies," Heather Conley, senior fellow at the American Enterprise Institute, told the Journal. "The question mark is how the United States would respond in that case."

The Munitions Problem Nobody Wants to Talk About

That question mark is larger than most officials will admit publicly, and the reason is sitting in warehouses that are increasingly empty. Years of supplying Ukraine — combined with the ongoing US military campaign against Iran — have severely depleted American stockpiles of precisely the weapons that would be needed to respond to a Russian attack on a NATO ally.

US officials told the Journal that critical munitions at risk include long-range Precision Strike Missiles (PrSM), Army Tactical Missile Systems (ATACMS), and short-range Stinger surface-to-air missiles. These are not optional extras in a NATO contingency. They are the backbone of any rapid US reinforcement package for the Baltic states or Poland — the most likely targets of any Russian probing action.

Here is the uncomfortable arithmetic: the same weapons Washington has been sending to Kyiv for three years are the ones it would need to make good on Article 5. And they are running low. Moscow knows this. So does every defence ministry from Tallinn to Warsaw.

The Testing Has Already Started

If you are looking for signs that Russia is already probing NATO's boundaries, you do not have to wait for autumn. In July, a Russian drone crossed into Romanian airspace and was shot down — the second such incident in two days. In May, Russian drone debris struck an apartment building in Galați, eastern Romania. Last September, fragments from a Russian air defence missile landed in Polish territory. On August 8, a drone of unknown origin exploded roughly 100 metres inside Bulgarian territory, near a compressor station on the Trans-Balkan gas pipeline.

Meanwhile, Lithuania's military intelligence warned on August 6 that Russia is considering strikes on Baltic infrastructure using Ukrainian-manufactured drones — a false-flag mechanism designed to blur attribution. The Institute for the Study of War noted the same day that Russia regularly violates Baltic airspace and may use Ukrainian UAVs specifically to "test NATO's response."

None of these incidents triggered Article 5. None of them were meant to. They are calibration exercises — measuring reaction times, testing political will, establishing precedents for what NATO will and will not treat as an attack. Each unanswered provocation lowers the threshold for the next one.

What Putin Actually Wants

The strategic logic is not complicated. Putin's core war aim — preventing Ukraine from integrating into Western security structures — has already failed. NATO is larger than it was in February 2022, with Finland and Sweden now members. Western military aid to Ukraine, while slower than Kyiv needs, continues to flow. Russia cannot win the war it started. But it can try to win the next one before it begins.

A limited NATO attack serves multiple objectives simultaneously. It tests whether the alliance's most important member — the United States, distracted by Iran and politically fractured at home — will actually honour its treaty obligations. It exposes the gap between NATO's rhetorical unity and its material readiness. And it creates a precedent that Article 5 is a political decision, not an automatic mechanism — which is precisely what Moscow needs to demonstrate to fracture the alliance over time.

The target matters less than the response. If Russia can show that the United States will hesitate, negotiate, or calibrate when a Baltic ally is under attack, then the foundational assumption of collective defence collapses. Not overnight — but enough to make every NATO member east of Berlin recalculate its own security arrangements.

The Uncomfortable Truth

NATO was built for a world where the threat was unambiguous and the response was automatic. A Soviet tank column crossing the Fulda Gap would have left no room for interpretation. A cyberattack on Estonian banks, or a "little green men" incursion into Latgale, or a missile that happens to land on Polish soil — these exist in a grey zone that the alliance's founding documents were never designed to address.

The US intelligence assessment is not a prediction that Russia will conquer a NATO capital. It is a prediction that Russia will create a crisis designed to reveal whether collective defence means what the treaty says it means. And the uncomfortable truth — the one nobody in Brussels or Washington wants to say out loud — is that we do not actually know the answer.

Putin intends to find out.
