In 1981 Peres was against Begin's plan to bomb Saddam Hussain's nuclear reactor because he was worried about the diplomatic trouble it would cause between Israel and France who were building it and he was planning to go to the media tell them Begin's plan. As a result Begin had to order the attack earlier than planned to head off Peres before he could destroy it all. So because he was worried about how this would affect Israel in the eyes of the rest of the world he was willing to let Saddam Hussain get a nuclear weapon. In the end the entire world, US included did condemn Israel and the UN passed a resolution condemning Israel for it but at least Saddam didn't get a nuke. Ten years later when those same countries who condemned Israel for attacking Saddam's nuclear facilities were very grateful for Israel's actions because they sent their soldiers to invade Iraq to get Saddam out of Kuwait, if he had a nuke back then he may well have used it, think of all the hundreds of thousands of western soldiers who would have been killed if he had got his nuke and used it. Once again Peres is the diplomat and all that matters to him is image and diplomatic fallout if Israel does do something. Today the west is against an Israeli attack but I wonder how they will feel 5 years from now or less when Iran has not just a nuke but has increased the range of its missiles so they can hit not just Israel but every inch of Europe and mainland America because its inevitable that will happen eventually because they are developing more advanced missiles with longer ranges all the time and one day in the not to distant future they will be able to hit just about anywhere in the world then Iran won't be an Israeli problem it will be a global one and we will have a new Cold War era position where we are all pointing nukes at each other just waiting for one side to press the red button.
