The Japanese defeated the Russians in a somewhat large war over the control of certain territories by the two countries.

This caused the President to offer peace terms that did not give either side an unbalanced share of rewards, to leave competition.
  • The Great White Fleet

    The Great White Fleet
    Roosevelt wanted to implement his "Big Stick Policy," which involved creating a large Navy intended to enforce United States' policies. This fleet consisted of 16 battleships which sailed around the world as a show of dominance.
