You will not find any American politician who does not lean on the side of the Israelis because the Jewish support is very important. Muslims have to start looking beyond Israel for a solution to the problem in Palestine because Israel is only interested in continuing the theft of Palestine. In the Qur'an we find the advise of "do not be divided amongst yourselves". That is where solutions to Muslims' issues lie. Until Muslims are able to come together to solve the challenges of fellow Muslims and others around them, they will be chasing a mirage thinking the US or any other country can be the solution.
That said, all I have to lean on is which politician is able to address my concerns keeping it local as trying to find one that will ever address the Israeli theft of Palestinian property is futile.
