I think sometimes one has to allow for poetic licence - as we truly don't know what situation(s) drove the writer to compose the song.
Also if my memory serves me right, for example the Falklands "War" as it is often referred , was in fact a "conflict" as I understand that "War" was never formally declared .
Some things written when the Muse visits may look completely different 20 or so years after they're written ,so whilst it might be a good topic of discussion ,especially of widely different points of view - he song stands , and will be sang as often as the writer feels comfortable.
Everyone is entitled to write his own version of the events discussed herein, and I wish you good luck in doing so.
Another example Roger Whittaker made a lot of money singing about Durham Town (it's a City) being on the banks of the river Tyne (it actually sits on the river Wear) but we don't beat ourselves up over technicalities and mistakes.
We're grown-ups,we understand such things and we move on.
