To those who complain that "Israel's nuclear arsenal is a threat to the region..." you are mistaken. Israel has had nuclear weapons... WITHOUT threatening any neighbors with warfare of any type. Israel acts to defend its nation... unfortunately, some of its activities, such as raids in the West Bank or Gaza, appears as offensive activity. Since there is no control in those areas, Israel must play the role of policeman for the Palestinians. Other than that, Israel does not pose any type of threat to anyone.
