Baltic states brace for hybrid warfare spillover as drone incursions trigger political and military upheaval
Suspected Ukrainian drone incursions into Estonian and Latvian airspace have exposed vulnerabilities in the region’s air defences, leading to cabinet collapses in Riga and heightened military readiness in Tallinn and Vilnius.
Estonia, Latvia, and Lithuania are reinforcing their borders with anti-tank ditches and concrete bunkers as fears of a direct military confrontation with Russia intensify. The physical sense of distance from the war in Ukraine has eroded following a series of suspected Ukrainian drones veering into Baltic airspace, an event Ukraine attributes to Russian electronic jamming while Moscow denies responsibility. These incursions have triggered public alerts, political turmoil, and a surge in military preparedness across the region, with defence budgets rising and exercises becoming more frequent.
The instability was most acute in Latvia, where the ruling coalition collapsed following the government’s handling of the drone incidents. Then-Prime Minister Evika Silina dismissed Defence Minister Andris Spruds over criticisms regarding slow military responses and air defence gaps, a move that ultimately led to Silina’s own resignation. The political fallout coincided with a drone exploding at an oil storage facility in Rezekne and raised concerns about social fractures that Russia could exploit, particularly regarding language policies and the integration of the Russian-speaking minority.
In Estonia, officials have marked 2027 as a critical benchmark for military readiness against a potential Russian threat. Lieutenant General Andrus Merilo warned that Russia is rebuilding its military faster than many Europeans realise, though the government maintains that Moscow is not preparing an imminent attack. Estonian authorities are countering hybrid tactics, including disinformation campaigns such as the "Narva People's Republic" narrative, while scrambling NATO fighter jets in response to Russian MiG-31 incursions earlier in the year.
Lithuania, which borders the Russian exclave of Kaliningrad, has seen anxiety drive both investment planning and family decisions. Former Foreign Minister Gabrielius Landsbergis noted that the rate of drone incursions is currently manageable, but severe escalations remain a possibility. Public opinion polls indicate that 76 percent of Lithuanians view Russia as posing hybrid threats, with significant anxiety preceding Belarusian-Russian military exercises near the border.
Uncertainty regarding NATO’s commitment to collective defence has been exacerbated by shifting US foreign policy. In May, President Donald Trump announced the withdrawal of 5,000 troops from Germany and initially scrapped plans to deploy 4,000 troops to Poland, before reversing course to deploy an additional 5,000. Meanwhile, US Under Secretary of State Thomas G DiNanno reportedly sidestepped direct questions on whether the US would defend the Baltic states if invaded. In response to these geopolitical shifts, NATO is accelerating the deployment of acoustic sensors, drone interceptors, and jamming systems along its Eastern Sentry mission.
