European leaders and intelligence services have highlighted Russia's intensified hybrid operations against NATO members, including drone incursions near Poland and Lithuania, sabotage attempts in Germany and Poland, and airspace violations, as part of efforts to strain alliance unity and redirect support from Ukraine. Danish defense intelligence assessed in late September a low but growing risk of limited long-range strikes or small-scale incursions into bordering NATO states within months, while deeming a full invasion highly unlikely though not impossible. Russia escalated rhetoric with a nuclear warning tied to Kaliningrad in late September, prompting NATO to reaffirm its defensive posture and reject any imminent territorial threat. Recent NATO military engagement in Kyiv and ongoing Ukrainian strikes underscore persistent conflict dynamics that could influence escalation risks through the resolution window.
