Questions about the defense of the West

This blog is a call for the defense of the West. However, in order for this call to be a coherent one, several questions must be answered. I will try to address them in subsequent posts. The answers will be considered to be a work in progress, and may be changed, if circumstances warrant.
These questions include:

What is the West?
Why must the West be defended? - what are the threats to the West?
Why must the West be defended? - why defend the West at all?
How should the West be defended?
Is it possible to declare victory in the defense of the West, and under what conditions would Defenders do so?

Other questions will be explored, as they emerge...
