In your opinion, what made the Declaration of Independence successful and a failure?

In my opinion, the Declaration of Independence is a founding document of American history. The successful thing that made the Declaration of Independence was when it states that people have certain basic rights and that the government should protect those rights. If the government did not support their rights, the people had the right to rebel. Also, how it lists the colonists' complaints against the British government.Then, it declared that the colonies are free and is an independent states. There were signers of the Declaration as representatives of the American people. They declared the colonies independent from Great Britain. The failure was it wasn't a social contract, it didn't create any form of government. It was a statement justifying the American Revolution and it was force of law to separate the colonies. Also, it failed because the declaration was almost forgotten entirely and it failed to accomplish some things and didn't remain faithful.
