"Targeting civilians is a war crime. Accidentally killing or maiming them in the pursuit of legitimate military objectives is, well, just too bad."

The English expression of COLLATERAL DAMAGE (damage that is unintended or incidental to the intended outcome) was birthed into our vocabulary base after 1945.

COLLATERAL DAMAGE is an English expression now accredited to a General in the United States Air Force and the vice presidential running mate of American Independent Party candidate George Wallace in 1968. George Wallace's inaugural speech in 1963 as Governor of Alabama used the line for which he is best known:

“In the name of the greatest people that have ever trod this earth, I draw the line in the dust and toss the gauntlet before the feet of tyranny,
and I say segregation now, segregation tomorrow, segregation forever."

segregate: 1542, from L. segregatus, pp. of segregare "separate from the flock, isolate, divide," from *se gregare,se "apart from" (see secret) + grege, ablative of grex "herd, flock." Originally often with ref. to the religious notion of separating the flock of the godly from sinners. Segregation (1555) is from Late Latin segregatio, from Latin segregatus; in the specific U.S. racial sense it is attested from 1903; segregationist is from the 1920s.

Curtis Le May (the presidential running mate of George Wallace) used the term collateral damage in reference to the bombing of Japanese cities in the Second World War.
