Could it happen in the US??

Everyday we read about war in countries that the US is always trying to prevent and protect people in other countries for wars that they are having between themselves. What if that war started happening in the US. Bombing and killing of masses of people. What would the people do and what would the country do? Would other countries come to the aide of the US. Would there be Human bombers here bombing place of government and military. Would the US be able to control that from happening to the US?/?
