It is awkward discussing an incident if folks have passionate views on the topic but if someone threatens you with a gun, do you assume it is not loaded?
If an unauthorised military aircraft invades or accidentally flies into our airspace when our country is at a high state of security alert, then do we assume it is unarmed and has no hostile intent? Is there any way we can tell it is unarmed? Bank robbers get shot when they wave around toy guns.....
Unfortunately for Turkey their aircraft entered the airspace of a nation that is having major internal problems and that aircraft was in the wrong place at the wrong time.
