Several German MPs from both the ruling and opposition parties have backed the idea of allies defending Ukraine’s western airspace from NATO territory, Frankfurter Allgemeine Zeitung (FAZ) reported.

FAZ wrote that some experts, such as Nico Lange of the Munich Security Conference and Lieutenant General Heinrich Brauss, a former NATO deputy secretary general, have suggested shooting down Russian missiles over Ukraine’s border regions from Poland and Romania. Polish officials have also mentioned this possibility, but no concrete decisions have been put forward.

“Defending the airspace over Ukraine from Poland and Romania should not be ruled out in the long term,” said Anton Hofreiter of the ruling Greens party. The outspoken MEP added, however, that the issue is “not on the table” at present, as the allies are focusing on providing additional defense aid to Kyiv.
