Speaking alongside his French counterpart, Jean-Noël Barrot, a guest of honor at Poland's Heads of Missions Conference, Sikorski pointed to what he called hostile Russian activity, including cyberattacks, sabotage, arson, attacks on railway infrastructure, drone incidents and the use of Russia's shadow fleet to map critical infrastructure. His comments come as Poland, a NATO frontline state and key hub for Western military aid to Ukraine, has repeatedly warned that Moscow could use hybrid operations to test the alliance without triggering full-scale war. Sikorski has previously raised the risk of a false‑flag operation, warning that Russia could manufacture a pretext for escalation and drawing a direct parallel to the 1939 Nazi Gleiwitz incident, a staged attack on a German radio station that Hitler used to justify the invasion of Poland. “We know what you're planning. Don't do it,” Sikorski told Moscow publicly. “The aim of these warnings is to deter them from carrying out these provocations.”
