German-Dutch Corps Takes Responsibility for NATO Eastern Flank in Estonia

Background: Tasks and Structure of the Corps

In addition to Germany and the Netherlands, 14 other NATO allies provide personnel for the corps. Leadership rotates regularly between Berlin and The Hague. Pistorius described the corps as an „Erfolgsgeschichte" and at the same time emphasized: „Dies zeigt: Wir sind bereit, größere Verantwortung für Europas Sicherheit zu übernehmen."

The deployment on the eastern flank is part of a broader NATO disposition plan. Germany is permanently establishing a combat-ready brigade of up to 5,000 soldiers in Lithuania by 2027. In addition, Germany and the Netherlands had already established a new headquarters for enhanced deterrence on the eastern flank a week before the NATO summit in Ankara.

Security Situation on the Eastern Flank

Estonia and Latvia border Russia directly, and Latvia additionally borders Russia's ally Belarus. According to their own statements, both Baltic states are investing significantly in their defense this year: Estonia intends to spend 5.4 percent of gross domestic product, Latvia 4.73 percent. At the same time, both countries have agreed on the joint procurement of the German air defense system Iris-T, as air defense is considered a weak point of the Baltic states.

During the Ukraine war, there have been repeated drone incidents in Estonian and Latvian airspace. According to the governments in Tallinn and Riga, these involved misdirected Ukrainian drones that entered the airspace of the Baltic states during attacks on targets in northwestern Russia. There were no major damage or injuries. Russia had repeatedly accused the Baltic states of making their airspace available for Ukrainian attacks; Latvia had even been threatened with retaliation following such accusations. The governments in Tallinn, Riga, and Vilnius rejected the accusations as unfounded and condemned the threats, while the EU and NATO expressed their solidarity.

Tensions Over Burden-Sharing Within the Alliance

Against this backdrop, the handover takes place during a phase of tense debates over burden-sharing within the alliance. US President Donald Trump and his administration have repeatedly accused European NATO allies of doing too little for their own defense and continuing to rely on the United States. US Defense Secretary Pete Hegseth announced a six-month review of the US troop presence in Europe and stated: „Und deshalb verstärken wir unsere Bemühungen, die Nato zu dem zu machen, was sie immer sein sollte: ein ausgewogenes Bündnis, in dem Europa die Führung für seine eigene Verteidigung übernimmt: Nato 3.0."

With the handover, NATO will in the future have two tactical headquarters on its eastern flank. Until the NATO summit in the following week in Ankara, the deployment is considered a further building block of enhanced forward defense, which has been discussed since the 2023 summit in Vilnius. The German Air Force also regularly takes over NATO air surveillance over the Baltic states and deploys fighter jets as well as personnel to the region.
