What The Preamble Means

The Preamble states,"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

This introduction to the constitution outlines what the document as a whole means to Americans and the inalienable rights people have while living in this country. To me, the assertion means that these are the aspects that the government will provide its citizens with.
