Russia’s Hybrid Warfare: The Real Threat to NATO

The ‘Unsinkable Aircraft Carrier’: Why Gotland is Central to Baltic Security

In the high-stakes game of geopolitical chess in the Baltic Sea, one location stands out: the Swedish island of Gotland. Often referred to as NATO’s “unsinkable aircraft carrier,” Gotland’s strategic positioning makes it a critical asset for any force seeking to dominate the region and defend the Baltic states.

The importance of the island cannot be overstated. Control over Gotland is viewed as the key to safeguarding Estonia, Latvia, and Lithuania, providing a vantage point that can effectively seal or open the Baltic Sea to military movements.

The Debate: Direct Seizure vs. Strategic Posturing

There is a growing divide among security experts regarding how Russia might actually “test” the alliance. Swedish Chief of Defence Michael Claesson has issued stark warnings that Moscow could execute a “land grab” on Gotland at any time. According to Claesson, such a move might not even be extensive in scale, but rather a political maneuver to test NATO’s cohesion and resolve.

However, not all experts agree that a direct military strike is the most likely path. Jakub M. Godzimirski, a researcher at Nupi, suggests that Sweden may be overly eager to place itself on the “threat map.” Godzimirski argues that the Baltic states—Estonia, Latvia, and Lithuania—remain the areas where Russia poses a more significant direct threat.

The Rise of Hybrid Warfare: The Recent Front Line

While a full-scale invasion of a NATO member would likely trigger a major power war in Europe, many analysts believe Russia is pivoting toward “hybrid warfare.” This approach allows an aggressor to undermine a society from within while maintaining a level of deniability.

Hybrid warfare is defined as a sophisticated blend of conventional military operations and irregular tactics, including:

• Cyberattacks: Targeting government systems and critical infrastructure.
• Sabotage: Physical attacks on energy or communication lines.
• Influence Operations: Spreading disinformation to erode public trust.
• GPS Jamming: Disrupting navigation and transport systems.

Case Study: The Polish Experience

Poland serves as a primary example of these tactics in action. Polish Foreign Minister Radoslaw Sikorski has explicitly stated that Poland has been subjected to Russian hybrid warfare. This has manifested not only as GPS jamming and infrastructure interference but also through the use of agents employing violence to cause harm.

The ‘Trump Factor’ and Internal NATO Fragility

External threats are only half of the equation. The stability of the transatlantic partnership—the bedrock of European security—is facing internal pressure. A significant point of concern is the unpredictability of U.S. Policy, specifically regarding the influence of Donald Trump.

Experts like Jakub M. Godzimirski point out that the uncertainty surrounding the U.S. Commitment to the transatlantic cooperation creates a vulnerability. If allies doubt that the U.S. Will stand behind the alliance, the deterrent effect of NATO’s collective defense is weakened.

The Article 5 Threshold

The ultimate deterrent is Article 5, the guarantee that an attack on one member is an attack on all. Hiski Haukkala, Director of the Finnish Institute of International Affairs (FIIA), notes that testing territorial integrity or Article 5 is an extremely grave action that would rapidly escalate into a large-scale conflict. Because the “Russian threshold” for such a move remains high, hybrid threats are seen as the more probable tool for testing NATO’s limits.
