Rogue nations led by brutal dictators who hate us, and have the means to destroy us, do indeed infringe on our freedom. They are a 'clear threat' to our security and freedom to live as we choose.
btw, the Soviet Union was discovered to have been not nearly the threat as we supposed it was before the Iron Curtain fell...............their 'stockpiles of weapons,' as it were, and capability not as strong as we were led to believe by their bluster.
There isn't a "rogue nation" out there with "the means to destroy us." North Korea has, at most, a few nukes; the Soviet Union had thousands. Yet we were able to defeat the Soviet Union without ever invading or engaging in a global crusade for democracy.
