Should we nuke any country that opposes the United States?

Personally I think we should not nuke any country that opposes the untied states, because that would give us an image that we probably should not have or want. We are the only free country and we believe that you are not bound by strict rules like being forced to be a certain religion. Now if we were to nuke a country just because they oppose us, wouldn't we be going against everything that the constitution and bill of rights are for? Now if we go against that than in my opinion we do not deserve to be called americans and we should be ashamed of ourselves. Now on the other hand if they, for example bomb us or pose a threat to any american then but then and only then do we have the right to give them the beat down of a life time and royally kick their (excuse my language) ass. So under certain circumstances do we have the right to nuke opposing countries but not just for having different views.
