The Palestinians would not be there if the Israelis did not hire them as cheap labor the same way that ten million illegal immigrants in the US would not be there if the government were not paid to look the other way. The sad truth is that middle eastern Jews are genetically identical to the Palestinians and one in five Israelis is Muslim.
Its not about race or religion, but corruption promoting racial and religious inequality and strife because it makes money. If every Jew in Israel were to leave today the Muslims would simply start killing one another. Its also similar to blacks in America now killing cops. They have been so disenfranchised and marginalized that the gun does all the talking and they know the only way to get better treatment is to make it too expensive to treat them like garbage.
