"It is also important to note that FATCA’s requirements are the same for all American taxpayers—expats are treated no differently.

Mark J. Marzur, Assistant Secretary for tax policy, United States Treasury Department

(1) The Master Nationality Rule says that every country has the right to consider their resident citizens as only their citizens and not the citizens of any other country; (2) the Dominant Nationalty Rule says that a so-called dual citizen has the right to protection of the country with which they have the closest ties; and (3) The Rule of State Non responsibility, a state, has no right to protect a citizen–or steal from them–if they are currently inside a country in which they have citizenship. FATCA conforms to none of the international rules of dual citizenship.
The above statement of the Assistant Secretary raises a serious moral issue. If the US Treasury wishes to ignore international law, then it is the United States which is involved in the illicit activity.
