Answer:
The framers of the Constitution would offer several arguments for keeping the list of individual states in the Preamble. First, they would argue that the states are sovereign entities that have come together to form a federal government. Second, they would argue that the states are the primary units of government in the United States and that the federal government is a creature of the states. Third, they would argue that the states are the source of all political power in the United States and that the federal government is a limited government with specific enumerated powers.
The framers of the Constitution would offer several arguments for replacing the list of states with "the United States" in the Preamble. First, they would argue that the United States is a single entity composed of many states. Second, they would argue that the United States is a federal republic, and that the federal government is the supreme authority in the country. Third, they would argue that the United States is a nation with a single people, and that the federal government represents the interests of all Americans.
One example of how the goals stated in the final version of the Preamble are carried out by our government today is in the area of national defense. The federal government provides for the common defense of the United States by maintaining a military force and by entering into treaties with other countries.
