Lithuania's new prime minister Mindaugas Sinkevicius, 42, is attempting something structurally difficult: running a Social Democratic government on NATO's most exposed border while insisting that defense and social policy are not competing priorities. In an interview with DW, he laid out a security doctrine built on self-reliance within alliances, air defense as the top national priority, and the framing of Lithuanian airspace as indivisible from NATO's. The interview's core claim is strategic: "Lithuanian skies are NATO skies." This is not decorative rhetoric. It is an attempt to raise the cost of allied indifference by making Lithuania's vulnerability a collective problem. If a drone from Belarus breaches Lithuanian airspace, Sinkevicius wants that treated as a breach of the alliance's airspace — not a bilateral incident on a small Baltic state's border. Sinkevicius rejected the drones-versus-tanks framing that has become common in European defense debates, insisting both are necessary. More interesting was his pivot from hardware to social cohesion: "Neither drones nor tanks will protect us if society does not feel safe, if people do not feel a connection with the state." This is a Social Democrat making a national security argument for welfare spending — linking unemployment support and healthcare to deterrence credibility. On Ukraine, Lithuania has committed at least 0.25% of GDP annually, with actual spending running around 0.3% of GDP according to Ukrainian-cited figures. Sinkevicius acknowledged war fatigue across Europe but reframed it sharply: "If we Europeans feel tired, then what must Ukrainian society be feeling?" He singled out Germany and Western European states as critical to maintaining the support front. The Nordic-Baltic Eight (NB8) framework received a quiet but significant mention as a regional coordination mechanism. For Lithuania, this grouping — linking Scandinavian defense capacity to Baltic vulnerability — represents a hedge against slower NATO-wide decision-making. It is sub-alliance architecture built for speed. The interview also revealed the political tightrope Sinkevicius walks domestically. He expressed concern about far-right and populist gains in Western Europe while noting Social Democratic governments hold power in several countries. The subtext: center-left parties that fail to credibly address security will lose ground to populists who promise toughness without the fiscal discipline. The structural tension is clear. Lithuania is spending heavily on defense and Ukraine support as a percentage of GDP, while its PM insists social spending cannot be sacrificed. The math only works if allies — particularly larger Western European economies — carry proportional weight. Sinkevicius is betting that framing Lithuanian security as NATO's security will keep that pressure alive.
