The true cost of operation Cast Lead is that when Israel starts shouting "WAR CRIME!! WAR CRIME!!" and pointing fingers, Israel will now be ignored. The Israeli defense for their own war crimes of pointing their finger and saying "what about them?" will increasingly be turned against Israel. Fingers will now point back at Israel and ask "what about you?" every time Israel accuses their enemies of war crimes. This is the true price Israel will continue to pay for Operation Cast Lead.
