Here is how and why the US declared our right to self-govern (CAPS mine)
'We hold these truths to be self-evident, that ALL men are created equal, that they are endowed with certain INALIENABLE RIGHTS, that among these are life, liberty and the pursuit of happiness.
That to secure these rights, governments are instituted among men, DERIVING THEIR JUST POWERS FROM THE CONSENT OF THE GOVERNED. That whenever any form of government becomes destructive of these ends, it is the RIGHT OF THE PEOPLE TO ALTER OR ABOSISH IT and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness.'
.... of course we had to fight a tyrant to obtain these rights. So the DecIndep ends.
'And for the support of this Declaration, ..we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.' and our Revolution started!
