Talking about "collective punishment". This is what Shimon Peres said the 14th of January 2009: Speaking to a delegation from the Israeli lobby Aipac, President Shimon Peres confirmed that "Israel's aim was to provide a strong blow to the people of Gaza so that they would lose their appetite for shooting at Israel" These are his words. Note, he did not say "provide a blow to HAMAS". If you don't believe that these are his exact words, I can send a video link, where you can see him pronounce these words.
