North Korea has nuclear weapons (dirty nukes at a minimum). Iraq very likely has dirty nuke capability. Many of these countries would love to "test" one of their weapons on America via what they think are untraceable terrorists. We have to let them know it will be traced and repaid in kind a thousand fold. Otherwise sooner or later the unthinkable is going to happen. Only fear at the root level in these terrorist supporting countries will stop it from happening if it can be prevented at all.
I don't think you realize just how close we are to something nuclear happening in America. Offending or enemies along with a few friends is a small price to pay to help prevent this from happening. The stakes are far too high.
So what facts do you have other than government propaganda attempting to scare you out of your freedoms?
Think outside the box a bit and tell me if you can see how some of the nuttier countries would perceive this as a threat of sorts rather than some sort of offensive statement??????????????????? Can you see how one of those countries could be provoked to attack us because we appear to be threatening them?????
