Unless the United States is prepared to lose its Arab allies, such as the Saudis and other petroleum producing countries as well as completely disregarding the Palestinians, and abandoning them in the solution to the conflict, which it would not be able to withstand. Furthermore, this is occupied territory from the 1967 War which established occupied lands in which settlements continue to be built. Jerusalem is an occupied territory so the US would be ignoring the Geneva Conventions and possibly violating such laws. The only way to get a resolution and settlement is to have leadership in Washington that is prepared to have a President to pay the price of not getting the second term as well as members of Congress losing their seats. This will frankly make the resolution process much more difficult.
