NATO's Massive Air Force Drill Sends Message to Russia.

NATO has launched its largest-ever air force drill, "Air Defender," involving 25 countries, 10,000 personnel, and 250 aircraft, to send a message to countries like Russia that it is ready to defend every inch of Allied territory. The two-week-long exercise is aimed at boosting interoperability and preparedness to protect against aircraft, drones, and missile attacks on cities and critical infrastructure. Meanwhile, Ukrainian troops have reportedly retaken seven villages from Russian forces over the last week.
