Military operations against civilians is a war crime no matter how you want to spin it.
Sometimes you have to look at the circumstances that led up to that killing.
The bombing of Dresden occurred after years of fierce war where the outcome was many times in doubt.
Actually Dresden was basically a tit-for-tat for Coventry. You destroy cities, we will destroy cities. Ugly but it seems to have worked, neither side went in for city-wrecking after that.
The firebombing of dozens of Japanese cities and the atomic bombs come after years of the same.
That was a different case--the Japanese industrial infrastructure was so dispersed that the only way to destroy it was to destroy the cities it was in. Valid military target.
And the fate of Palestinians in Gaza is just as much in doubt.
It is very easy when you are not being oppressed and attacked if any amount of resistance is shown to say what is absolutely moral and immoral.
No. Immoral remains immoral even if you're the underdog.
I still can't believe that your justification for the attempted ethnic cleansing of an entire people, is based on the fact that people who get bombed a lot don't always react well.
The only side that's trying to do ethnic cleansing is the Palestinians.
