Lithuania and Baltic States Strengthen NATO Defense and Strategic Cooperation

Lithuanian President Gitanas Nausėda visited the Baltic Defence College (BALTDEFCOL) in Tartu, Estonia, on March 27, 2026, to emphasize the strategic importance of the defense partnership between Lithuania and the United States.

The visit took place at a location situated approximately 50 kilometers from the Russian border, serving as a backdrop for discussions on the strengthening of NATO’s eastern flank and the necessity of national and regional security cooperation.

The U.S.-Lithuania Strategic Partnership

During his address, President Nausėda described the transatlantic bond with the United States as central to the future and security of the Baltic states. He stated that the relationship must remain productive and mutually beneficial to continue enhancing defense, cooperation, and national resilience.

The transatlantic bond with our closest ally— the United States—remains central to the security and future of the Baltic states. We must maintain a productive, mutually beneficial relationship that will continue to strengthen our defense, cooperation, and national resilience. I believe this partnership can grow even stronger, not only in the military sphere but also in economic and energy cooperation.

President Gitanas Nausėda

Nausėda identified energy diversification as a primary example of this cooperation. He noted that 70% of Lithuania’s liquefied natural gas imports are sourced from the United States and delivered via the Klaipėda LNG Terminal.

Regional Defense and Deterrence

Military cooperation remains a critical component of the regional strategy. Previous coordination among Baltic defense leadership has highlighted the role of the U.S. Army as a cornerstone of regional security. On April 16, 2025, the defense chiefs of Lithuania, Latvia, and Estonia met at the Baltic Defence College to discuss implementing defense policies.

Gen. Raimundas Vaikšnoras, commander of the Lithuanian Armed Forces, has emphasized the importance of rotational U.S. Forces in Lithuania. Specifically, he highlighted the support provided by two U.S. Battalions from the 1st Brigade, 3rd Infantry Division, based in Fort Stewart, Georgia.

Beyond direct military presence, Lithuania utilizes the State Partnership Program with Pennsylvania to develop its forces, a cooperation that Vaikšnoras noted has existed for 30 years.

Lithuania is also working to consolidate cooperation with Germany, specifically with the 41st Panzergrenadier Brigade, which is expected to be fully mission-capable by 2027. These efforts are part of a broader strategy to enhance regional deterrence involving the Baltic states and Poland.

Addressing Hybrid Threats and Resilience

The Baltic states face a variety of hybrid threats that necessitate increased societal resilience. According to reports from the Congressional Research Service, these threats include:

• Disinformation campaigns
• Cyberattacks
• Sabotage
• Weaponized migration

In response to these tactics, NATO leaders have worked to increase cooperation among member countries to counter hybrid warfare. The Baltic states have specifically sought to strengthen their internal resilience to mitigate the impact of these non-traditional security threats.

The Baltic Defence College in Tartu serves as a NATO-accredited institution for professional military education, attracting students from across the NATO alliance and Partnership for Peace nations to address these evolving security challenges.
