In 2008, in a briefing to the Diplomatic Corps on Israel’s operations in Gaza, Israel’s Vice Prime Minister and Minister of Foreign Affairs stated:
I think that Israel is the only state in the world in which its Minister of Defense has today, during a time of almost war, met with the Attorney General, the Minister of Justice, and Foreign Ministry experts on international law, in order to speak about and understand the terms of proportionality in accordance with how the IDF [Israel Defense Forces] works and will continue to work on the ground. So, basically, it is not something that can be judged. I hope that the international community knows that we are trying to avoid civilian casualties, and that what is called “collective punishment” goes against our values and our system.
