Who's denying that? The problem is that this war crime somehow justifies the war crime of blowing up entire civilian neighborhoods, with the civilians still present, in the minds of some people.Essentially, though theoretically it doesn't have to. Regardless, we don't get to redefine words simply because the State does them. Murdering innocent civilians becomes "collateral damage," yet it's still one group of people killing innocent people. Sorry, still murder.
Just as firing unguided rockets into civilian homes and neighborhoods is a War Crime.
Not a war crime if the civilian area is in use by the military/militia is it, or don't you bother checking on what International law and the rules of war say on the subject. The only true war crime is the use of civilian areas to engage in war
