Unbekannte Drohnen dringen mit US-Atomwaffen in Luftraum nahe NATO-Stützpunkt ein

For those following this for a bit, what do you think it is?

Personally I have three:

A: Russia/China genuinely has something advanced that can evade anti drone measures

B: Its way less of a mystery than described and the answer is more than NATO countries don’t want to engage these

C: Its a western nation doing some kind of internal testing of a new drone.

So once again, these unidentified drones were pursued by a military helicopter, but intercept was unsuccessful? Does that seem odd? The Belgian military operates the Airbus H145 helicopter, top speed is 165 mph.
