The embassy is the business address within Washington DC (city state). That city state along with the other two (London and Vatican) are the three states that control the planet. The Vatican is the feudal master and head, London controls the financial aspect and Washington DC is the corporate and military branch of the empire.
I speak about the feudal state within my book and I've also mentioned feudalism within my blog along with books that you can read. A Treatise on Copyhold and Blackstone Commentaries are two that I recommend. They both explain the feudal system in place today which I've given an outline within my first book "Graduating Life with Honours"
