NATO is weighing a stronger and more assertive response to what it calls an increase in hybrid attacks by Russia. These attacks include cyber intrusions, sabotage, and violations of national airspace, which have raised concerns across Europe. The alliance’s top military officials are now discussing ways to counter these hybrid attacks more proactively rather than simply reacting after the damage has been done.
Rising Hybrid Attacks Across Europe
Since the beginning of the conflict in Ukraine, Russia has been accused of carrying out hybrid attacks across Europe. Hybrid attacks combine traditional military methods with covert actions such as hacking, disrupting communications, and even damaging critical infrastructure. In recent months, Europe has seen a number of such incidents.
There have been incursions by drones and fighter jets, suspected sabotage on key railways, GPS jamming, and damage to undersea cables. One notable event involved an explosion on a major rail line in Poland, which was condemned as an act of “state terrorism.” Many European officials have linked these hybrid attacks to Russia’s efforts to intimidate Ukraine’s allies and weaken support for Kyiv.

NATO’s military leaders say these hybrid attacks are becoming more frequent and sophisticated. To deal with them, the alliance is now considering a shift in strategy. Instead of waiting to respond after an attack occurs, NATO could adopt a more proactive stance. This could even involve actions that are considered preemptive, though officials stress these would be framed as defensive measures.
Proactive Measures Under Consideration
NATO is exploring the use of offensive cyber capabilities, rapid response drills, and other measures to deter Russian hybrid attacks. Officials have said that a preemptive strike could be considered defensive if it is aimed at preventing an imminent attack. However, such moves go beyond NATO’s traditional ways of acting and raise legal and ethical questions.
Legal constraints are a major consideration. For example, a Finnish court recently dismissed a case against the crew of a Russian vessel suspected of cutting underwater cables, ruling that the act took place in international waters. This has highlighted how difficult it can be to hold aggressors accountable in international law, even when damage is caused by hybrid attacks on critical infrastructure.

Despite these challenges, NATO has also seen successes in deterring hybrid attacks. One key initiative, the Baltic Sentry mission, has deployed patrol ships, surveillance aircraft, and naval drones in the Baltic Sea. The goal is to prevent sabotage of undersea cables and other critical infrastructure in one of Europe’s most sensitive maritime regions. Since the mission began, no new sabotage incidents have occurred, suggesting that deterrence can work when properly implemented.
Officials stress that adopting a more assertive posture does not mean acting recklessly. Any proactive actions would require careful planning, clear rules about which countries would carry them out, and consideration of ethical and legal limits. Alliance members are aware that they operate under stricter rules than their adversaries, making decision-making complex.
NATO’s Strategic Challenge Amid Hybrid Attacks
The central challenge for NATO remains how to best protect Europe from hybrid attacks without overstepping legal or ethical boundaries. Officials say that every option is on the table, from retaliation to preemptive actions, but each comes with its own set of risks and responsibilities.
Hybrid attacks are particularly difficult to counter because they often fall into a gray area between war and peace. Attacks can be carried out remotely, anonymously, and without warning. Cyberattacks, for instance, can disrupt communications, energy grids, and transportation systems, while sabotage of infrastructure can have long-lasting economic impacts.
European nations are increasingly considering coordinated responses, including joint cyber operations and surprise military drills. These measures are aimed at signaling to Russia that hybrid attacks will not go unanswered. At the same time, officials caution that actions must be measured and carefully calculated to avoid unnecessary escalation.
NATO leaders continue to analyze the situation closely. While the alliance is known for its defensive stance, there is growing recognition that hybrid attacks may require new strategies. The discussions reflect a shift toward a more assertive posture in order to protect critical infrastructure, maintain stability, and deter potential aggressors.
