"Western" Military Invincibility: Is there a "west" and and is there a System?

Follwoing a discussion last week with a host on Tuesdays, many topics came up but were flat-out denied by the host.  Some things were even made up as he went along.  Points were addressed with proof and quickly shut down, but the originator of the idea of a 'western military heritage' refused to accept his L.  So now we must go deeper into what was discussed to put an end to all of the BS (hopefully) once and for all!
