Let me first tell you one thing: It doesn't matter what the world says about Israel; it doesn't matter what they say about us anywhere else. The only thing that matters is that we can exist here on the land of our forefathers. And unless we show the Arabs that there is a high price to pay for murdering Jews, we won't survive.
As quoted by Ariel Sharon, in the documentary The 50 Years War : Israel & The Arabs (1999), this advice was given to him by Ben-Gurion after the controversial raid on Qibya.
