**Analysis**
The text appears to be discussing the development and proliferation of nuclear weapons, their characteristics, and potential implications for military strategy and tactics. It mentions various types of missiles, basing modes, and delivery systems, as well as the potential for precision-guided munitions to change the nature of nuclear warfare.
