Answer: Jerusalem is very strategically placed
Explanation: The Babylonians, Romans, Persians, Arabs, Fatimids, Seljuk Turks, Crusaders, Egyptians, Mamelukes, and Islamists (and others) had control over Jerusalem at some point and time. Jerusalem was very prosperous and Israel overall was (and still is) a wealthy nation. Another reason control of Jerusalem is such an issue is that it is a central part of three of the world's major religions: Christianity, Islam, and Judaism. This is a very high point of tension and has been disputed for the last thousand years. This issue was what began the Crusades, and it is a central part of the tension regarding Jerusalem now. As far as what I would do to help solve it is a difficult question, an impossible question even. In an idealistic world, we could make peace with the boundaries NATO put into place after WW2; however, this is very unrealistic, and quite frankly I believe there is very little that can be done. This issue has gone unsolved for thousands of years.
