......... I’m pretty sure NATO does not have the power or jurisdiction declare No Fly Zones over non NATO Nations ......
I’m pretty sure they could do so at the request of that country’s government...
NATO enforced a No-Fly Zone over Bosnia (then part of the former Yugoslavia) from 1992 to 1996. Then in 1999, NATO waged a 3-month air war to crush the Serbian government. For two decades when we were the only great power, we did whatever we wanted to whomever we wanted, and nobody could lift a finger to stop us. Now it appears the Russians have had enough of our meddling on their borders.
serbia?
