The best answer to this was given by Secretary Rumsfeld:
“Rumsfeld, speaking with reporters in Munich yesterday, was asked why the United States is silent when “Israel has more nuclear arms than any other nation in the world.” Rumsfeld said, “You know the answer by yourself, and the whole world knows the answer. Israel is a small country with a small population. It is a democracy, but exists among neighbors who want to see her in the sea. Israel has made it clear that she does not want to be in the sea, and as a result, over several decades, has organized in such a manner so as not to be thrown into the sea.”
Rumsfeld for President!!!!
