To take a purposefully provocative analogy: yes, during World War II, the Allies (even excepting the Soviet Union) committed war crimes. The strategic bombing of Germany and the atom bombing of Hiroshima and Nagazaki were war crimes. Elizabeth Anscombe was right to denounce Truman. It nonetheless remains true that if you lived through World War II and pretexted of Allied crimes to portray the sides as morally equivalent, or to refuse to take sides, you were guilty of moral cretinism and cowardice.
This is a conflict where there really are Good Guys and Bad Guys and to pretend otherwise is indefensible. The chief culprit of the plight of the Palestinians is not Israel but the terrorists and fanatics who use them as tools of their ravenous bloodlust.
Golda Meir was right then, and is right now. The conflict will end when the enemies of Israel start loving their children more than they hate Israel.
Yes, it really is that simple.
