The U.S. Department of Defense on Thursday issued a classified memo directing the immediate suspension of all joint military exercises with NATO members in Eastern Europe, a move that has triggered urgent consultations among allied governments. The directive, first reported by Reuters and confirmed by three U.S. Officials with direct knowledge of the order, marks a sharp departure from the Obama-era policy of maintaining a consistent rotational presence in the region. The memo cites “operational realignment” but provides no public rationale, leaving allies to speculate about its implications for collective security.
German Foreign Minister Annalena Baerbock expressed “deep concern” in a statement, noting that the decision “undermines the credibility of the transatlantic bond.” A senior NATO official in Brussels described the move as “unprecedented in the post-Cold War era,” emphasizing that the alliance’s 2010 Strategic Concept explicitly states that “collective defense remains the cornerstone of NATO’s purpose.” The suspension affects training drills involving the 2nd Infantry Division and the 1st Cavalry Brigade Combat Team, which had been conducting annual exercises in Poland and the Baltic states since 2017.
White House spokesperson Karine Jean-Pierre declined to comment on the memo’s contents but reiterated administration support for NATO’s Article 5 clause, which obliges members to consider an attack on one as an attack on all. However, a separate memo obtained by The New York Times reveals that the Pentagon’s Joint Chiefs of Staff had recommended scaling back such exercises in January 2023, citing “resource constraints” and a shift in focus toward Pacific theater readiness. The documents, which include internal assessments from the U.S. European Command, do not mention Russia directly but note “evolving strategic priorities” in the context of rising tensions with China.
Poland’s Ministry of Defense has initiated emergency talks with U.S. Military attachés, according to a report by Polish public broadcaster TVP. “We are seeking clarity on the long-term implications for our security,” said a Polish official, speaking on condition of anonymity. Meanwhile, the Baltic states have begun reviewing contingency plans to bolster their own defense budgets, with Latvia’s parliament voting unanimously to increase military spending by 15% in March. Lithuania’s defense minister, Raimundas Karbauskis, warned that the U.S. Decision “risks creating a security vacuum that could be exploited by adversarial actors.”
The abrupt reversal has also intensified scrutiny of Senator Marco Rubio’s recent statements. In a March 15 speech at the Atlantic Council, the Florida Republican argued that “NATO’s current posture is too reactive” and called for a “more strategic approach” to European security. While Rubio’s remarks were widely interpreted as critical of the Biden administration’s policies, a direct link between his comments and the Pentagon’s directive remains unproven. A spokesperson for Rubio’s office declined to comment on the matter.
NATO Secretary-General Jens Stoltenberg is set to convene an emergency meeting of the alliance’s North Atlantic Council on April 5, the first such gathering since the 2022 invasion of Ukraine. The agenda will include a review of collective defense arrangements, though sources indicate that discussions will focus primarily on cyber resilience and maritime security rather than the immediate troop withdrawal. A draft statement obtained by Bloomberg suggests that the alliance may issue a reaffirmation of its commitment to Article 5, though it stops short of addressing the U.S. Policy shift directly.
