Answer:
In 1783, the United States had a much more hands-off approach to foreign policy. The country was too young, and was not very developed yet, and this meant that the U.S. government was primarily interested in keeping the country internally stable.
By 1828, the United States had become a stronger and wealthier country, and was becoming more active in foreign policy matters. To start, in 1812 it launched a war against Britain for the control of Canada, which it lost, and by 1828, the U.S. had the goal of taking much of the Northern territories of Mexico.
