To all the people saying there isn't an easy solution: you are wrong, the solution is actually very easy, easier than most international problems. It's the solution the entire political world has been willing to get behind for 50 years or so. If I remember correctly it's that Israel return to its 1967 borders and get rid of its nuclear weapons. Every couple years the UN votes on this, the results are always like 230 to 2. The whole world agrees, except for Israel and the US, and the US vetoes it every time.
Imagine getting 99% of the world to agree to something, and thinking the problem is too complicated to solve.
