im not sure what your trying to say, your just talking in riddles.
history of war as least in Europe did not involve the purposeful targeting of civilians, up until the 2nd world war to be accurate the Spanish civil war, which was the curtain raiser
Actually it did, wars have always targeted civilians. the Crusades killed hundreds of thousands of civilians. Armies laid waste to farmland and crops, rape and pillage aren't modern. 'Scorched Earth' was an accepted part of warfare. Raiding parties were common from all cultures, tribes and groups etc. In wars towns were sacked, often in reprisal, most times just because they belonged to the 'enemy', history is littered with civilian deaths. The Greeks and Romans both targeted civilians, as did many armies afterwards.
Oh and for the record, Great Britain wasn't at war with Japan at the time of Pearl Harbour, Churchill declared war on Japan because of pearl harbour.http://www.ibiblio.org/pha/policy/1941/411208d.html
