Why does the UN and G8 allow Israel to commit Genocide?

One word, AMERICA. America fully and wholeheartedly supports Israel and won't give a damn if Israel wipes out every non-Jew in the entire Middle East. The hatred of non-Jews by Israeli extremists is shown in the bombings of innocent civilians and the US is glad because their MASTERS in Israel will give them access to oil. Yeah, I said masters, the United States is the puppet of Israel and wouldn't dare tell them if their actions amount to genocide.
