Russia Threatens Systematic Strikes on Kyiv While Europe Fears a NATO Confrontation and U.S. Support Frays

Within a day, however, senior Russian figures began softening the message. On 26 May, State Duma Defence Committee Chairman Andrei Kartapolov claimed Russia was not actually threatening to strike the Ukrainian parliament or presidential office, asserting that those buildings are not the “real” decision-making centres . The Ukrainian Foreign Ministry called the original warning “blackmail” and said the overall threat level to Kyiv was unchanged . Western embassies largely ignored the evacuation call, and Kyiv residents described the threats as “nothing new” .

European fears: could Russia test NATO within one to two years?

The rhetoric and the missiles over Kyiv are unfolding against a deeper, more structural European anxiety. In May 2026, several national security officials told The Wall Street Journal they fear Vladimir Putin may try to “reshuffle the cards” by expanding the conflict beyond Ukraine — and that Russia could test NATO’s cohesion within the next year . Potential scenarios include strikes on Baltic countries, Swedish or Danish islands, or alliance territory in the Arctic .

Dutch military intelligence (MIVD) published an even sharper timeline in its April 2026 annual report: Russia could be ready to start a regional conflict with NATO within a year after hostilities in Ukraine end. Crucially, the report judged Moscow’s objective would not be to defeat NATO militarily but to split the alliance politically, using limited territorial gains — under a nuclear threat if necessary .

EU defence officials and lawmakers told Politico the same month that Russia may see the next one to two years as an ideal window to test NATO, while President Trump remains in office and before Europe significantly strengthens its own military capabilities . Finnish MEP Mika Aaltola said bluntly, “Something could happen very soon – there is a Russian window of opportunity” .

These warnings fit a longer pattern. Germany’s Inspector General Carsten Breuer said in June 2025 that NATO should prepare for a possible Russian attack by 2029 . NATO Secretary-General Mark Rutte warned in December 2025 that Russia could attack a NATO country within five years . German Defence Minister Boris Pistorius and other alliance generals have pointed to a window of 2027–2030 for a possible Russian move against NATO territory — while European rearmament plans will not close critical capability gaps until 2035 .

Not every analyst agrees that a deliberate Russian military attack on NATO is the most likely scenario. A January 2026 EU Institute for Security Studies commentary concluded that a direct NATO-Russia war remains unlikely in 2026, and that the greater risk lies in “slow-burn actions that steadily degrade Europe’s security environment while remaining below NATO’s Article 5 threshold” . The Eurasia Group similarly forecast that the most dangerous front in 2026 would be the hybrid war between Russia and NATO — infrastructure sabotage, airspace probes, election interference — rather than a conventional invasion .

The U.S. drawdown: not just fewer troops, but fewer wartime promises

The third crisis is the Trump administration’s active reduction of the U.S. military posture in Europe. This goes beyond the rhetorical pressure of previous years and now involves concrete troop withdrawals, deployment cancellations, and a planned reduction in pledged crisis capabilities.

On 1 May 2026, the Pentagon announced it would remove about 5,000 troops from Germany within six to twelve months . President Trump signalled possible reductions in Spain and Italy as well . Then on 14 May, Defense Secretary Pete Hegseth went further, abruptly cancelling two scheduled U.S. military deployments to Europe and ordering the removal of other personnel — including a planned rotation of the 2nd Armored Brigade Combat Team through Poland and the Baltic states .

Just as significantly, in late May 2026 the administration was preparing to tell allies that the U.S. would shrink the pool of military capabilities it would make available to NATO in a major crisis . Three sources told Defense News the Pentagon had decided to “significantly scale down its commitment” — this is a reduction in pledged wartime forces, not simply a peacetime rebasing . Euronews reported the total U.S. presence on NATO territory stood at about 76,000 troops before these cuts, down from roughly 80,000–100,000 at various points since 2022 .

Legal and political friction exists. A 2026 U.S. defence law does not prohibit troop withdrawals outright, but it requires detailed consultation and justification for cuts that push the total below 76,000 for more than 45 days . President Trump has nonetheless said the U.S. will go “a lot further” than the 5,000-troop reduction already announced .

A dangerous convergence

The EU Institute for Security Studies has described today’s Europe as facing “the most dangerous security environment in decades” . What makes the moment especially fragile is the alignment of three distinct but mutually reinforcing trends:

• An emboldened Russia. Moscow is combining a sustained air campaign against Ukraine with open threats against Kyiv, and using the post-ceasefire period to posture for domestic and international audiences .
• A recognised window of vulnerability. European intelligence and political leaders widely believe Russia could act against NATO territory well before Europe’s rearmament programmes produce decisive new capabilities — a gap that stretches into the 2030s .
• A shrinking American backstop. The Trump administration is not simply reducing the headcount in Europe; it is signalling that the United States would provide less military power in the very scenario European allies fear most — a crisis that tests Article 5 .

The scenarios mapped by the Atlantic Council — including possible Russian seizure of territory in Norway, Finland, or Estonia — are exercises in planning, not predictions . Dutch intelligence explicitly frames any Russian conflict with NATO as a political operation aimed at dividing the alliance, not a bid for military victory . But even without a deliberate attack, European officials are quietly advancing contingency plans for a “European NATO” that could maintain deterrence should U.S. support wane further .

What is clear from the range of open-source assessments is that no single timeline commands consensus. Some European intelligence chiefs warn of readiness within a year after a pause in Ukraine; NATO generals point to 2027–2030; other analysts expect hybrid rather than conventional escalation to dominate 2026. But across almost all of the assessments, one judgment is shared: the alliance is entering a period in which its cohesion will be tested in multiple dimensions at once, and the old guarantees can no longer be taken for granted.
