"Obviously, the destruction of nuclear facilities could have more of an impact than any other attack, by causing widespread radiation leaks. If anything, it could be more devastating than dropping a nuclear weapon, since the radioactive materials in these facilities often have a significantly longer half-life than what we see in atomic bombs."
Stop worrying Hey You, we know what we are doing. When Israel took out Iraq's nuclear facility years ago was there any radioactive fallout? Some so called Professor of God know what, is not an expert of nuclear weapons. We will take out North Korea's nukes, Iran's nukes, and Pakistan's nukes. And that will be that.
