After four years of war, Russian President Vladimir Putin has achieved a double failure: He hasn’t conquered Ukraine, or even its eastern Donbas region. And his attempts to intimidate Europe through sabotage and subversion have backfired, triggering strong pushback from European leaders.
Europe’s escalating resistance to Putin is an often-overlooked strategic factor in this conflict. Rather than being cowed by Russia’s “shadow war,” European nations are countering with their own disruption operations. Some European officials argue that Europe must now begin to plan seriously for the possibility of all-out war.
“Every missile and drone that strikes Ukraine only strengthens our resolve,” British Foreign Secretary Yvette Cooper said Tuesday during a visit to Kyiv. “Putin thinks that he can outlast the U.K. and our allies. He is sorely mistaken.”
Security officials from many major European countries have delivered similar warnings to Putin in recent weeks. They’ve announced new sanctions and called for tougher intelligence operations to counter Russia. This show of defiance is impressive in part because Europeans are acting largely on their own, without certainty that the United States will support their challenge to Moscow.
Russia “is preparing for the possibility of a conflict with NATO and is conducting activities to test the West’s willingness to escalate,” argued a Feb. 19 report by the Dutch intelligence agencies, titled “Between War and Peace.” The report described Russian arson, parcel bombs, disruption of air traffic and damage to undersea cables. To combat these actions, “the price has to go up, I think,” said Erik Akerboom, head of the Dutch foreign intelligence service, in September.
Blaise Metreweli, the newly appointed head of Britain’s MI6 spy service, made a similar warning on Dec. 15 in her first public speech. “Russia is testing us in the gray zone with tactics that are just below the threshold of war,” she advised, including “drones buzzing airports and bases” and “state-sponsored arson and sabotage.” She described the Russian efforts as “attempts to bully, fearmonger and manipulate,” and insisted that “countering this activity is the work of intelligence and security services across Europe and the globe.”
Britain backed up its rhetoric this week by imposing nearly 300 new sanctions on people and companies it accused of aiding Russia’s war effort. The list includes restrictions on some 50 ships in the “shadow fleet” that transports Russian oil and natural gas; bans on 175 companies linked with an Azerbaijani oligarch accused of aiding the covert fleet; and sanctions on 18 companies, many Chinese, that sell military or “dual use” products to Russia.
Germany, which before Putin’s 2022 full-scale invasion was often a docile partner of Russia, is pushing back, too. “The threat emanating from hybrid warfare has been recognized,” Martin Jaeger, head of the BND, Germany’s spy service, said this month at the Munich Security Conference. To combat it, the BND “must and will become more operational,” he said.
The German Defense Ministry has prepared an operational plan for curbing Russian hybrid operations, according to a Bloomberg report last month. Russian operations against Germany and other countries are “a tool deliberately used by Russia in its security policy and its fight against the ‘collective West.’ At the same time, these measures could also serve as preparation for military conflict,” the German document warned.
Putin apparently thought he could frighten Europe into accepting his assault on Ukraine. In a Feb. 24, 2022, speech announcing his war aims, he threatened: “No matter who tries to stand in our way … they must know that Russia will respond immediately, and the consequences will be such as you have never seen in your entire history.”
When Russia’s nuclear saber-rattling failed to stop Western support, Putin began his “hybrid war” campaign against Europe. According to a study by Leiden University, the number of these covert attacks rose from 13 in 2023 to 44 in 2024. The Estonian intelligence service warned at the end of 2024: “Since cutting off Western support is a key precondition for Russia to subdue Ukraine, the Kremlin has decided to raise the stakes by launching a deliberate campaign of sabotage against Western nations.”
But Putin badly miscalculated in assuming that Europe would retreat under pressure. The Estonian report explained: “Russia’s covert sabotage operations have consistently backfired, reinforcing the prevailing perception of Russia as a hostile force rather than achieving any strategic advantage.”
Europe’s first move was to expel Russian intelligence officers — as many as 600 have been removed, according to a report last year by the consulting firm Globsec — who were organizing covert plots. To fill the gap, the Globsec report said, Russia turned to what it called a “spook-gangster nexus” to mount operations, often recruiting online. Of the more than 130 “hybrid” operatives identified in the report, at least 35 had criminal records. Online recruitment was used in 55 percent of the cases.
What does the European pushback look like? A report on Russia’s shadow war shared with me by a leading private intelligence firm describes a string of European countermeasures over the past few months.
In September, the French Navy intercepted the Boracay, an alleged Russian shadow fleet tanker. In December, Finland seized the Fitburg, a cargo vessel that had allegedly disrupted an undersea telecommunications cable. In January, Germany banned an alleged shadow-fleet tanker called the Arcusat. Later in the month, France seized the Grinch, another alleged shadow fleet tanker. This month, Denmark seized Nora, a vessel that had allegedly carried Russian oil.
European countries are also rounding up Russian-linked saboteurs, according to the private security report. In October, Poland and Romania arrested eight alleged members of a sabotage ring that was preparing parcel-bomb shipments to Ukraine. In December, Lithuania temporarily closed Vilnius airport after balloon incursions. In January, Poland arrested five people in an alleged Russian plot to mail incendiary packages to the United States, Britain, Canada and Lithuania.
The Europeans have even tracked the Russian shadow war in space. According to a Financial Times report this month, European security officials identified two Russian satellites, Luch-1 and Luch-2, that may have intercepted communications from European satellites.
Russia’s war grinds on, but the cost grows every month. Russian casualties are nearing 1.3 million dead and wounded. The country’s economy is unraveling. Russian statistics show that oil revenue declined 24 percent last year. The country’s financial balance sheet has gone from a surplus in 2021 to a deficit of more than $70 billion last year.
Putin’s war, as it enters its fifth year, is a case study in the law of unintended consequences. He invaded Ukraine to erase a hostile nation on his borders. But he united Ukrainians against him, creating what will be many decades of anti-Russian hatred. Similarly, he covertly attacked Europe to compel submission but instead aroused a new defiance and commitment to defense.
The Estonians, on Russia’s border, have an intimate appreciation of Russia’s catastrophic mistake: “The Kremlin fails to recognize that acts of vandalism, arson and other physical hostility … only reinforce Russia’s reputation as an aggressor and strengthen further Western unity against Moscow.”
In the annals of what historian Barbara Tuchman described as “The March of Folly,” Putin’s blunder in Ukraine belongs near the top of the list.
