Trigger happy is firing willy nilly. The Navy were ordered to fire regardless of identification. That’s different.
Is it? Surely, the end result is exactly the same; opening fire on ‘any aircraft within range regardless of identification’? The Royal Navy gunners may have been ordered to do this, and those that ordered them to do so may have felt justified, but that doesn’t alter the end result one iota.
I understand that you have a personal involvement and I meant no disrespect by using the phrase ‘trigger-happy’ but it does seem to describe exactly the actions of Royal Navy gunners…
…even if they were following their orders to the letter.
