Psycho leaders taking the world to the edge

After renewed efforts of the hawkish US administration to develop new generation of (mini) nuclear weapons as well as developing the so-called Missile Defence System, Russia is now getting back to this dangerous game which not long ago was thought to be coming to an end: Russia working on new nuclear weapon system. This system could include a missile designed to defeat the US missile "defence" system.

Indeed these powerful crazy world leaders are taking the world to the points where there might not be any return from. Why do the peaceful world people have to be constantly worried about the actions of bunch of psychos?
