Too true, but it is the only road to victory. I am not saying that Israel has to see a true victory today, or ever. That is their choice, knowing that they will be vilified around the globe if they do. But, if I were a leader in Israel, and I had seen decades of terrorist attacks by a group that is sworn to kill me, my wife, my children, my grandchildren, etc - I might be willing to take the global heat.
Imagine that a man is standing in front of you. He has a weapon, but you have the advantage. He has sworn to kill you and your entire family. He means it, and you know it. He will pass his hatred down to his children and grandchildren. Your family will never be safe if you let him go. You can kill him and protect your family from him forever, but you will go to jail and be viewed as a murderer by the entire world. What would you do?
That is the choice that the Israeli people have faced for decades. They keep hoping that these groups will die out or ease up, but that isn't happening. Eventually, they will kill the terrorists - and they will be vilified for it...
