Q: How many nations, isolated geographically, geopolitically, health wise, and educationally, does it take to do irreversible damage to the planet?.......A:ONE....... NORTH KOREA. How much longer,and how much further can we allow one rogue state to hold the world as hostage? If not in a technical way, a psychological one. It's gone on for more than a half century...how much longer? Is a situation such as that, fixable in any traditional way? Proliferation of all things bad, nation wise is what their ruler(s) are into. When will the rest of the world stand up to them, and talk to them with some tough love? To hell with their ripped off "Don't Tread On Me" attitude. That ship sailed a few hundred years ago. Let's act before it's too late.
