When does the POTUS get to nuke somebody?

The real story concerns Schlesinger, the SecDef and is very telling on several levels. I found an account which is quite readable.

This is an interesting study in how power worked in the Nixon White House, and shows how people interact on the cabinet and JC levels.

Which is the exact reason why I posted a link from them. To rebut Strangers assertion that Command and Control was somehow not known. The fact is that there have been continuous public discussions on this issue since about 1998.
