Complete History of the United States (1941) Part 2: Lead the present with friendly hand toward the future.

I read the last 5 pages and you should, too.  The author believes the US will and should relinquish Pacific concerns in exchange for hegemony in the Americas.

 The last sentences  -- page 564 - of the book are as follows:

It takes almost mysticism to see that out of this bleeding chaos a dancing star will be born.  Americans are strengthened in this mysticism by returning to the words of one of their major prophets, Walt Whitman:

O days of the future I believe in you -I isolate myself for your sake, 

O America, because you build for mankind I build for you,

O well-beloved stone-cutter,  I lead them who plan with decision and science,

Lead the present with friendly hand toward the future.

I like it.
