Wow, so should we give the US back to the Native Americans? How about all other conquered land in the world? I mean how far back would you like to go?
If Israel goes back to the 67 boarders there still will not be peace. Was there peace after Israel gave back all of the captured land after the six day war, no. Was there peace after Israel gave back the Gaza Strip, no. Why would this be different?
Nothing will change and if you think going back to the 67 boards will help you are flat out wrong.
