what standard do you need to be breached for a war to be literally a war to you. the coal miner i met you got shot in the leg charging a machine gun nest called it "our civil war." he trained with a rifle, got on a train to Mattewan, charged a machine gun nest, got bombed, and had to contend with "riot control gas."
to him, it was a war. and given the scope and scale of what happened on blair mountain, i reckon, i'd say it was a war.
