When Jonathan Schell heard all that loose talk about attainment of objectives in a limited nuclear war, it was too much for him and he did what all of us would like to do: he wrote a book. It is very pessimistic. The mere presence of all those weapons is enough to ensure that sometime, somewhere, someone is going to set one off. Schell makes sure all of us know the horrendous possibilities of a nuclear exchange and all the reasons for bringing such possibilities to a halt. Everyone agrees. The question is, how do we get these monsters under control?
