I would advise you to do your own research but I'll give you a few hints.

There are three "city states" in the world that are cities that reside within countries but are sovereign states within a country.

Vatican City, a Sovereign state apart from Italy (Head of the fractionalized banking cartel world wide)

City of London, not to be confused with London, UK but a sovereign state apart from the UK, (the Rothschild banking empire, lapdogs of the Vatican)

Washington DC, a city state that is sovereign, a district of Columbia (which was one of the names being considered during the formation of the USA) also a lapdog for the Rothschild banking empire and thus controlled by the Vatican, ultimately.

Also, research the US military war guide for occupying foreign capitols and what laws they must follow when occupying foreign territory.
