The world still breeds hate

Its incredibly tragic what still exists in the world today. Graffiti artist/master Banksy recently trekked to the wall on the Israel/ Palestinian border. Banksy, who is among my favorite artists, creates fantastic works of art that are provocative and delicately placed. Im not sure what he was trying to accomplish here, and it sounds like the work wasn't recieved well by either side. Possibly he wanted to brighten the bleakness of the situation. My question is why does the world continue to sit back while this happens? Were the jews themselves not treated horribly not half a century ago? Its despicable to create this wall of hate....Look at this beautifully tragic work on his site, and please make a difference, speak up.
