What is the main idea of this short excerpt and what actions did the Japanese gov't take to restore values?

The Japanese are a truly ancient people. Very little of japanese culture changed for 1000 years until the industrial revolution. Then British and American interests saw asia as a good place to develop. Starting in the mid 1800's Japan became more modern and was striving to catch up with the west. this drew very mixed feelings among the people. They saw the british empire taking India and China and felt they needed to go on the offensive before it was too late. Hence they sided with the Nazis and went to war.
