"but as long as isreal has them and uses them to blac kmail other nations those other nations will want them." - the bomb I have never seen Israel 'blackmail' anyone with it's presumed nuclear capability. I think a persuasive argument may be made that Israel's capability has been a stabilizing factor in the region. The last major war was almost 40 years ago after a period of 25 in which there were 4 major wars. As a results none of the neighboring countries of Israel have pursued nuclear weapons. They have a perfect excuse to not attack, and two have made peace treaties with Israel.
