How 'bout a siege of the District of Columbia?
Shut down all routes into the foreign city-state.
Let no truck deliveries in.
Let no government workers, politicians, lobbyists out.
DC is foreign to America.
It is run as a plenary oligarchy.
It has long ago extended its tentacles beyond the 1 mile square it is supposed to stay within.
Through deception, fraud and legal chicanery.
Repeat, DC is a foreign city-state.
