This is the part that is law:
That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do.
We said that was how it was, the British legal system disagreed and so we had a war.
We won by the way.
And then the British signed a piece of paper that said we were no longer their property and that, by being a treaty, became law.
And then we had another war because they had their fingers crossed on some parts. We won that war too.
It ended with another treaty.
And this time they stuck to the terms and so we are now friends.
