[...] Congress itself can punish Alexandria, by repealing the law which made it a town, by discontinuing it as a port of entry or clearance, and perhaps by suppressing it's banks. But I expect all will go off with impunity. If our government ever fails, it will be from this weakness. No government can be maintained without the principle of fear as well as of duty. Good men will obey the last, but bad ones the former only.
