Not so much repetition as continuation.  Expansion (i.e.,
imperialism) has been the theme of the growth of this country from
the beginning, and control of resources and markets is the
requirement of an unbridled capitalist juggernaut which cannot exist
without expanding indefinitely.   It's all about getting a good
return on your investment, whatever it takes.

Mark my words!
(there's the Twain connection, in case you were wondering.)
