Final answer:
If the government doesn't do its job of protecting the people's rights, their right is to overthrow the government through revolution.
Step-by-step explanation:
The quote from the Declaration of Independence that you provided states that if the government fails to protect the rights of the people, their right is to overthrow the government. This means they have the right to revolution and can establish a new government that will protect their rights. This idea was deeply influenced by philosophers like John Locke and is a core principle of democratic governance.
