"How do you fell about taking out Iran's nuclear capability before they have a chance to use them?"
Iran is not to be confused with a law abiding American citizen who is exercising his 2nd Amendment rights. Iran is a part of the Nation of Islam, our mortal enemy.
Whether they have nuclear arms or not, they are a threat and need to be broken, just as Iraq and Afghanistan needed to be. Iran has said what they will do with their bomb, and it isn't self defense. They plan to destroy Israel who is not just our ally, but our holy land as well.
