The European branches of my family thought America would become a threat to the global balance of power if not addressed.  They hurt us.  The South did not recover from the legacy of the Civil War for generations.  But in the North, four years of war production boomed into a hungry civilian sector.  We exploded into the Western Territories, men and women seeking to leave the war behind them, with a drive that terrified Europe.  They were right to be afraid of us.
