What analogy does Paine use to compare the attack of Britain on the American Colonies?

From the outset, Paine makes it clear that he is not particularly fond of government, whose sole value he thinks lies in "restraining our vices". For Paine, the natural state of man is to live without government, and government's existence is justified only to the extent that it alleviates problems that would be created by this natural, anarchic way of life. If a government fails to improve society or, worse, actively causes some of the same troubles that would result from anarchy, it is particularly blameworthy.
