Roosevelt revolutionized the U.S. Presidency. Many credit him with establishing the modern presidency. Speaking softly and carrying a big stick meant that American power was to be respected in domestic and international contexts. As president, he was a negotiator and peace maker as demonstrated in his successful negotiation of the Russo-Japanese War (1905), for which he won the Nobel Peace Prize. He also played an important role in Progressive Era Reforms such as the Pure Food and Drug Act.

This meaning belongs to "the Monroe doctrine"<span />
The Spanish-american war allowed the United States to connect the two coasts and establish themselves as a force on the new continent. The expansion allowed them to have allies worldwide who traded with the states and this enabled them to accumulate wealth. World War 1 was the cherry on top because it ruined the entire economy of Europe as well as European infrastructure, while US was free to produce and export since it had no economic rivalry with anyone.
