The answer is The New Deal
The two-state solution is an idea that Israel and Palestine would live next to each other with secure borders and respectful of each other. The idea is noble and surely better than the situation that exists nowadays, however the prospect of success depends on their willingness to stick to a two-state plan that would be devised. It would be possible for a two-state solution to exist with the help of an international union like the UN to help enforce the idea of two-states.
