The United States invaded Grenada in 1983. This was to show that the United States would not allow a country to drop out of the free market system. Ronald Reagan was quoted as saying "it isn't nutmeg that's at stake." which was Grenada's biggest export. Meaning that the United States didn't want Grenada using it's resources to better help it's self but to help the United States.

The growth of the empire continued to increase their confidence.
