I have tried to find the text of the Rhodesian Proclamation declaring indepeendence in 1965, but I cannot. I refer you to this image, http://en.wikipedia.org/wiki/File:Rho-udi.jpg instead, which if you copy and enlarge will demonstrate that the renegade colony of Rhodesia claimed the same kind of justification for its illegal acts that the 13 colonies asserted for their own treachery almost 200 years earlier. It is, in fact, known that Rhodesia found the US Declaration of Independence to be the best model for its own intentions and therefore chose to model its Proclamation on that document.

But it is not only Britain that has been accused of such heinous misrule of wholly virtuous men, but the United States has itself, and by its own citizens, too. Senator John Townsend said that, "our enemies [the Abolitionists] are about to take possession of the Government, that they intend to rule us according to the caprices of their fanatical theories, and according to the declared purposes of abolishing slavery." This marked the first steps to the seccesion from the Union by the Confederate States, leading to the American Civil War. You might like to look at the Georgian Seccession document, for example.

The point I am making is that you can dress up any act - good or evil - so that it will appeal to the uncritical mind and will in some cases lead them to lay down their lives for an unjust cause, beliving they are acting entirely honourably.
