When there's fighting and killing on a big enough scale, what else do you call it but a war? "Troubles" is a good word to avoid silly arguments like this, but "war" is perfectly accurate.

After all neither the Korean War nor the Vietnam War nor the Iraq nor Afghanistan Wars involved any declarations of war, so it can be argued they should be called something else.

"Mildly offensive" seems strange to me. As if the very Mention the existence of prejudice or skin colour must be offensive.

Like many of Vin's songs this doesn't look great on paper, but when he sings it it's magic. Even if you can't understand the words half the time.
