But being "held responsible" and being "held accountable" are very different. Holding someone responsible means to blame them. Holding someone accountable means giving them consequences. Many people blame the government for all sorts of things. Only a very small number of those things is the government ever held accountable for.
I agree that many people blamed the British Government for their problems, indeed that was the impetus for the revolution, but accountability of the British government was limited to none.
