So the Russians were going to attack their own ships. Just like they blew up their own pipeline and bridge to Crimea.
An ISR platform, manned or unmanned, is considered neutral when flying in international air space when it is only observing. As soon as targeting data is shared with belligerents, the ISR platform becomes a co-belligerent and loses its neutral status.
IOW, look for another contrived incident. The US continues to poke and jab and stab at Russia, attempting to create an incident that can be used to escalate the war.
The neocons lust for Nuclear World War 3.
Note that a few weeks ago there was an incident over the Black Sea involving a Russian fighter jet, a missile launch, and a manned British ISR plane. And a few years ago, Iran shot down a Global Hawk encroaching on their air space. This can "get real" very fast.
