>Why the silence while the rest of the world condemns Israel and America?<

I believe Abbas described the Hamas rockets as "irresponsible."

>The Israelis have just killed about 300 people over an attack by Hamas which killed, what was it? 2 people?<

I don't follow the logic of "proportionate" response.

If you are going to use the machinery of government to kill people, the goals should be defined. That's elementary. The minimum goal is clearly defined: To stop Hamas-inspired violence against Israeli citizens in the near term. If that is the goal (or even if much larger and more nefarious motives are to be believed), then why would you revert to killing just two people or two hundred people if hostiles killed two of yours? Such numbers do not logically relate to any rational goal, legitimate or nefarious. That would be savage retribution and nothing more, with no "goal" of any kind.
