In certain circumstances where you are being oppressed, it is obvious that mediation, negotiation, etc. will not be sufficient in regaining your liberty and that revolting is the only way. Such real-life examples include the Amistad uprising in 1839, prisoner revolts at Sobibor and Treblinka during the Holocaust and the passenger revolt aboard Flight 93. Those revolts were more small-scale and had the intention of self-liberation as opposed to overthrowing a government. I agree that if governments act despotically, they need to be replaced. When it comes to overthrowing a tyrannical government, I think it's more complicated. People should only resort to revolution if all other means fail. The United States has checks and balances that prevent our government from becoming a dictatorship. Uprisings and coups usually occur in countries that are politically unstable.
