A Universal Danger
Man's ability to obliterate life on this planet has increased at a rapid rate.
We are faced with the deplorable prospect of new weapons that can cause 
destruction of life and property on a scale bar beyond our imagination.
No matter who takes the first step to initiate the conflict, the possibility
exists that conflagration will spread and envelop the world. Much thought
has given to ways and means of avoiding such catastrophe. Some consider it
is mandatory for the nuclear powers to seek agreement on methods of limiting
and controlling these weapons, for in absence of such agreement, we may
rue the day atomic energy was made practical.

come cross-country biking with us. He's blowing hot and cold on the
deal at this point.
