The coming oil war in the Middle East might well see the use of nuclear weapons.
If Iran is attacked (a totally insane act in my view) I think that the entire region will rise up against the Western powers. The West could not win in such a situation. They will be forced to withdraw and Israel will be left isolated to reap all the bad blood it has sown throughout the Muslim world. Israel will have no recourse but to threaten capitals such as Tehran and Damascus with nuclear annihilation. We are looking at dark days indeed.
