European defense ministers agreed last week to build what they called a “drone wall” along their borders with Russia and Ukraine to better detect, track and intercept drones violating Europe’s airspace. “The results of the (Ukrainian) mission in Denmark will shape the framework for cooperation with other European countries as well,” Zelenskyy said.
