This is how we do it - right here. By raising awareness of the problem.

These guys (who, in my opinion, are some of the biggest heroes in the world right now) are saying, and I believe they are one hundred percent right about this, that the way to do it is to continue to speak out and continue to raise awareness about this, until the public outcry is too great to be ignored any longer. These two former members of the Israeli military are saying that this situation is driven by public opinion in the United States and Israel. They believe that most people in both countries would not stand for what is going on if they knew the truth of what is being done to the Palestinians. When public opinion in the US against apartheid is too strong to ignore any longer, that's when the leaders of both the US and Israel will be forced to correct the problem. Until then, nothing will be done.
