NATO officials and former members have raised concerns about the threat from Russia, discussing the possibility of invoking Article 5 in response to severe cyber-attacks. Military leaders warn that Russia may test the alliance's resolve. Despite this, NATO isn't panicking, but it faces complicated challenges beyond conventional war. The alliance must maintain unity and credibility to deter Russia amidst growing uncertainty among its members. This concern is not just about Russia's actions, but also about NATO's ability to respond effectively. Experts say the situation requires careful consideration.
The current discussion revolves around "hybrid" activities, including cyber-attacks, sabotage, disinformation campaigns, airspace violations, GPS disruption, and drone incursions. Recently, NATO jets shot down a Russian drone violating Lithuanian airspace, and Denmark accused the Russian navy of firing flares at one of its helicopters in the Baltic Sea. These actions fall into a grey area between peace and war, creating uncertainty and testing political resolve without triggering an immediate military response. NATO faces a dilemma in responding to such provocative but ambiguous actions. The alliance's traditional deterrence strategy may not be effective in this scenario.
Some Western officials believe Russia's objective may not be to start a war with NATO, but to probe for weaknesses and identify areas of disagreement among allies. This would allow Moscow to play a longer game than some in Eastern Europe suspect. Deterrence is no longer just about tanks and missiles, but also about maintaining political unity in the face of continuous low-level pressure. NATO's credibility relies on the assumption that member states will follow through on their commitments if tested. Analysts emphasize that deterrence rests on perceptions of allied willingness and political resolve as much as military capability.
The commitment of Article 5, which states that an attack on one member is an attack on all, derives its power from credibility, not just legal wording. If a hostile state caused widespread disruption to critical infrastructure, it is unclear whether that would justify collective military action. For NATO planners, uncertainty itself can become a vulnerability. The alliance's credibility has rested heavily on the assumption that the US would lead any major response to aggression in Europe. However, this assumption has become less straightforward, and European leaders are increasingly focused on shifting responsibility for conventional defence towards European allies.
Recent policy debates have centered on reducing US military commitments in Europe, reviewing troop deployments, and encouraging greater European self-reliance. This does not mean the US is abandoning NATO, but it does mean alliance planners must consider scenarios in which American resources are stretched across multiple theatres and political attention is divided among competing priorities. The challenge for Europe is to adapt to a future in which Washington expects allies to carry a greater share of the burden. NATO's latest concept, "multi-domain operations," aims to orchestrate military activities across all operating domains and environments.
A second challenge for NATO lies within the alliance itself, where substantial differences in strategic outlook remain. Poland and the Baltic states view Russia as the central threat, while southern European members focus on instability in North Africa and the Mediterranean. Larger powers bring global interests that smaller allies do not necessarily share. The rise of nationalist and populist parties in Europe adds complexity, as these movements may support higher defence spending and tougher policies towards Russia, or be more sceptical of international commitments and multilateral institutions.
The consequence of these differences is not necessarily division, but increased diversity in how security threats are perceived and prioritised. Research identifies differing threat perceptions and domestic political interests as potential sources of tension within NATO decision-making. Experts interpret recent statements and proposals as evidence that NATO fears uncertainty, not war. The alliance must adapt to a transatlantic relationship in which European allies take greater responsibility for their own defence and preserve political cohesion among 32 states with increasingly diverse domestic politics and strategic priorities.

- NATO faces challenges from Russia's hybrid tactics, but isn't panicking.
- The alliance must maintain unity and credibility to deter Russia amidst growing uncertainty among its members.
