Drones Prompt Copenhagen Summit; Medvedev Warns

A Copenhagen summit convened after mysterious drone sightings in Denmark, where Ukrainian President Volodymyr Zelensky warned recent incursions and aerial violations in Estonia and Poland signal Russia is seeking to escalate and offered Ukraine’s expertise to help European countries build a “drone wall” to bolster defenses. European leaders, including France’s Emmanuel Macron and Romania’s prime minister, urged a firmer response to drones that violate airspace, saying such craft can be destroyed and should be treated as a serious threat. Russian President Vladimir Putin dismissed accusations and blamed rising European militarisation, while former Russian president Dmitry Medvedev cautioned Europe that a war with Russia would be unaffordable and carries an “absolutely real” risk of escalation to weapons-of-mass-destruction use. Policymakers at the summit are balancing heightened security measures with broader concerns, as a Scientists for Global Responsibility review warned NATO’s planned military spending increases could substantially raise greenhouse-gas emissions over the next decade. The debate reflects Europe’s scramble to deter spillover from the Ukraine war while weighing strategic, environmental and escalation risks of deeper military build-up.
