A more effective message to atomic North Korea : SETTING AN EXAMPLE ?

The mainstream news media is incapable of seeing nuclear arsenal hypocrisy here . Just a while back President Obama is standing on the grounds of Hiroshima offering no heartfelt apology for the horrendous deed .

 Just weeks ago I read about the U.S. preparing to spend a trillion dollars in coming years updating nuclear weapons missile systems.

I recall  reading a  book titled " The Arrogance of Power ", by Senator J. William Fulbright, while protesting our imperialist war in Vietnam in the late 60s.

Would not SETTING AN EXAMPLE be a more effective message to North Korea ? A revived nuclear disarmament program ?
