The power and wealth of the United States of America in the 20th and 21st centuries are the greatest in the history of mankind. Great Britain, likewise, was dominant on the world scene in the 18th and 19th centuries. These nations have dominated and influenced world events for over 400 years! How did the people of the United States and Britain become so powerful? Bible prophecy shows that the blessings are from God, and that in the future they will be removed.
