Europe Weighs How to Counter Russia’s Shadow War Without Triggering a Wider Conflict

Governments are shifting from protecting infrastructure to imposing costs, as suspected Russian sabotage in Europe tests how far allies can respond without triggering escalation.

European governments are confronting a growing security challenge: how to respond to suspected Russian sabotage in Europe and other covert operations that threaten infrastructure and support for Ukraine while remaining below the threshold of conventional war.

The immediate concern is that an incident could cause substantial loss of life, forcing NATO governments to make difficult decisions about retaliation. European officials interviewed by The New York Times said they did not expect a major Russian invasion of a NATO country, but described an escalating campaign that existing defenses have struggled to deter.

A campaign built on ambiguity

Recent incidents cited in the Times report include damage to Polish railway infrastructure, a Russian frigate firing flares at a Danish helicopter, factory sabotage, reconnaissance-drone incursions, and assassination plots targeting European defense executives. Attribution varies: some incidents have been directly linked to Russia, while others remain suspected operations.

Germany has publicly blamed Moscow for an attempted attack involving an explosive-laden drone found at Leipzig-Halle airport near Ukrainian transport aircraft. The drone failed, but the episode has intensified concern that Russian sabotage in Europe could reach civilian infrastructure.

David Cattler, a former NATO intelligence official, told the Times that Moscow was using operations designed to have an impact while avoiding a larger war. The intended effect, officials and analysts argue, extends beyond disrupting supplies to Kyiv: it also challenges public confidence that European governments can protect their citizens.

Moving from protection to consequences

In Europe, the emerging response to suspected Russian sabotage has three elements: publicly identifying responsibility, strengthening defenses, and imposing costs on the networks behind attacks.

Governments are investing in infrastructure protection and public preparedness. But resilience alone leaves Moscow choosing the time and place of the next incident, according to Linas Kojala of Lithuania’s Geopolitics and Security Studies Center.

Kojala argues that responses should also target the machinery of covert operations, including intelligence officers, proxy recruitment, and payment channels. Preparing funding and legal authority in advance could allow governments to respond faster rather than reopen political negotiations after every attack.

Alexander Gabuev’s analysis in the Financial Times offers a related caution: Russia has reasons to continue disruption beyond changing European public opinion, including interfering with military supplies and retaliating for support to Ukraine.

A collective answer to Russian sabotage in Europe

Agreement on consequences remains harder than agreement on protection. Decisions about covert operations and retaliation largely rest with national governments, complicating a unified European response.

Former U.S. ambassador to NATO Ivo Daalder told the Times that the alliance should prepare a menu of collective responses. He argues that NATO’s command structure makes it better positioned than the European Union to implement such measures.

Other suggestions cited in the report include cyber operations and intercepting threats over Ukrainian territory before they reach NATO countries. These are proposals, not evidence of an agreed retaliation policy.

The challenge is to make consequences credible without creating an uncontrolled cycle of escalation.

Nuclear rhetoric sharpens the stakes

That calculation is complicated by Russia’s nuclear warnings. At the Valdai Forum on Oct. 1, President Vladimir Putin denied plans to attack European countries but warned that Russia could use its full arsenal if Kaliningrad faced a direct attack. Russia also denies European accusations of sabotage and arson.

The warnings form the backdrop to renewed diplomacy. U.S. envoys Steve Witkoff and Jared Kushner were scheduled to meet Ukrainian representatives in Miami on Oct. 9, Reuters reported, with European, NATO, and EU officials also invited.

For Europe, the two agendas are closely connected: supporting a negotiated settlement while ensuring that attacks on its own territory carry consequences. Whether governments can agree on consequences for Russian sabotage in Europe before a deadly incident occurs is now a central test of their security coordination.
