a bonobo humanity?

This may be fact or fiction: a US drone, purposed for surveillance, and who knows what else, is flying in or near Iranian air-space, and is shot down. Iran is naturally the major suspect. Applying the shoe-on-the-other-foot test, if an Iranian drone, for whatever purpose, was flying in or near US air-space, would the US shoot it down? My vague guess is – absolutely, 100%. The USA and Iran are currently sworn enemies, for whatever reason. So this kind of drone behaviour would naturally be seen as a provocation and a threat. And just a bit rude.

This surely isn’t rocket science, it’s more like drone ethics. Or am I missing something here?
