A Jewish homeland is all that the Israelis want, not conversion of the entire world like the extremist Muslims. Why Israel was created and how is rather between the extremes, in my take from the History section of the following site: http://www.israelipalestinianprocon.org/ .
It is apparently very easy to become Islamic: all one has to say is that "I am a Muslim" to a witness. Once so identified, it becomes fatal, again in the Extremists' eyes, to fail that religious doctrine. Reading the Koran (in English, another blashphemy aparently) shows it regards compassion toward the less advantaged as one of the pillars, in giving alms to the poor. But criticize Islam, either from within or without, and it appears that Islam contains the ability to issue death threats that are grabbed up by a wide ranging population... see Salman Rushdie, for instance.
Islam as a whole for years didn't SEEM to have a problem with Judaism. It's the Zionists and their imperative to have the land once occupied by their ancestors that clogs the throats of Islam, especially at the cost of their brethren in Palestine/Israel. Objectively looked at, on the site listed above, the creation of Israel wasn't so black and white, but was deemed by many to be called for in light of widespread anti-Semitism over the years. When Israel finally did become a reality, there were shops, businesses, families existing next to each other that were both Jewish and Muslim, and they existed in a sort of dark harmony, but not overall in conflict. But it has been the governments of the Arab countries all around Israel, and others in the MIddle East and North Africa, that have several times tried to extinguish Israel. Never mind that the Arabic peoples have themselves been at odds with each other for centuries, even before definitive nations evolved. It leads one to see it all as: We are a family (Arabic peoples), and can fight and insult each other, but anyone outside pays dearly for that act. Distantly related, in my view, to some Blacks in the U.S. calling each other N****r, but having that derogatory epithet spouted by someone not within that racial definition considered (rightly so) heinous.
Islam already has a nuclear-capable entity: Pakistan. It is currently balanced, in no small part, by their neighbor and antipathetic power, India. And in Pakistan exists a great conundrum to the world that wants to see a democratic tide free numerous peoples: it is run by a military dictator. That he has worked with the forces attempting to quell the extremes of Islam in that corner of the world, has been friendly toward the U.S. and allies in a war on terror, doesn't negate the fact that he took power from the parliamentary process. The majority of people in Pakistan, I'm not sure what their stance would be on the world's troubles there. That the Pakistani bomb would be used if in the hands of the representatives of the majority there would be more likely. Where it would be used: local region, most likely. Would it be used against Israel? A greater liklihood if the powerfully opinionated in Pakistan had the power. A mirror, of sorts, of other Islamic powers' intents? Not out of the question. That is why allowing any other Islamic nation to possess nuclear weapons would ignite a conflagration that those of us old enough to remember was feared through the middle and late decades of the 20th century.
