Maybe some of the civilians did support their government and military, and maybe others were too scared to speak up. However, blind patriotism doesn't warrant being vaporized.
Perhaps not, but being on the losing side unfortunately does.
I don't believe that at all. Those civilians didn't deserve to be killed.
War is the clash of societies, not armies.
If killing the enemy's civilians gives strategic or tactical advantage then nations set out to kill enemy civilians.
Trying to find a moral path through a war is rather like trying to map a route through the wilderness with an alarm clock.
