If we had avoided killing inncent civilians during WWII, we might have lost the war. We killed thousands of innocent French civilians for example in bombing raids on French cities like Caen for example. Never mind the over a million German and Japanese civilians killed by our military.
The Israelis accidentally killing the innocent civilian did not invalidate the original effort to bring the murderers to justice. It's regrettable, but it happened. And as for the killing of the innocent civilian towards the views of the anti-Israel Europeans: do you honestly believe that would have made any difference in their anti-Israel sentiments if they had not killed him?
" do you honestly believe that would have made any difference in their anti-Israel sentiments if they had not killed him?"
Did I say that? I don't think I did.
