The primary objective of such an action would be to undermine alliance unity and test the resolve of individual member states, rather than to initiate a major war. One widely discussed scenario involves Russian troops launching a minor border incursion into the Baltic region. If NATO allies failed to respond robustly to such an incursion, it would challenge the credibility of the alliance’s core commitment to collective security and place its future cohesion in doubt.
These fears are grounded in a sustained pattern of Russian hybrid warfare and encroachments into NATO airspace. Over the past year, Russian drones have regularly violated the airspace of Poland, Romania, and other member states. In late July, a Russian cruise missile struck deep inside Polish territory, approximately 100 kilometers from the Ukrainian border. The escalation continued in early August with the discovery of an armed, explosives-laden drone at Germany’s Leipzig Airport, a key transport hub for military supplies to Ukraine. US officials assessed the device as belonging to Russian intelligence, while German Interior Minister Alexander Dobrindt described the incident as representing a “new level of danger.”
Critics argue that the Western response to these provocations has been insufficient, with many countries downplaying airspace breaches as isolated incidents rather than a coordinated campaign. This reluctance to impose significant costs on the Kremlin has fueled perceptions in Moscow of Western weakness. This dynamic mirrors previous episodes, such as the annexation of Crimea in 2014, where Western condemnation was not matched by decisive punitive action, leading to further Russian expansion in eastern Ukraine.
As these security threats mount, the geopolitical center of gravity for NATO is shifting eastward. Last week, Romania hosted the Bucharest Nine (B9) and Nordic Allies Summit, bringing together leaders from Central and Eastern Europe, Nordic partners, NATO Secretary General Mark Rutte, and Ukrainian President Volodymyr Zelenskyy. The summit, a preparatory meeting for July’s NATO Summit in Ankara, underscored that the eastern flank is no longer a peripheral security zone but a strategic center of the Alliance.
Discussions focused on the need for stronger air and missile defense capabilities, expanded defense investment, and closer coordination between allied defense industries. The concept of “NATO 3.0” emerged in informal discussions, describing a political understanding where Europe assumes greater responsibility for conventional defense and industrial capacity, while maintaining the United States as the indispensable strategic anchor. Polish President Karol Nawrocki emphasized that “there is no NATO without the United States,” reflecting a consensus that stronger European capabilities should complement, not replace, US engagement.
The summit coincided with Black Sea Defense Aerospace 2026, a major exhibition in Bucharest that drew participation from non-EU countries including Turkey, South Korea, and Israel. This participation signals increased interest in Europe’s expanding defense budgets and the rebuilding of transatlantic defense production ecosystems. However, the US presence in Bucharest was led by Under Secretary of State Thomas DiNanno, a lower political level than the strategic significance of the meeting might have suggested. This representation has reinforced ongoing European discussions regarding burden-sharing and the long-term sustainability of the US security commitment.
The immediate challenge for the alliance is to translate these political discussions into credible deterrence measures before further hybrid provocations or limited military incursions test the cohesion of NATO’s eastern and northern flanks.
