What part of the of the U.S. State Department Foreign Affairs Manual did you fail to understand where it said the following?
U.S. Foreign Affairs Manual, 7 FAM 1110 ACQUISITION OF U.S. CITIZENSHIP BY BIRTH IN THE UNITED STATES. . . 7 FAM 1113 Not Included in the Meaning of “In the United States” . . . c. Birth on U.S. Military Base Outside of the United States or Birth on U.S. Embassy or Consulate Premises Abroad:
(1) Despite widespread popular belief, U.S. military installations abroad and U.S. diplomatic or consular facilities abroad are not part of the United States within the meaning of the 14th Amendment. A child born on the premises of such a facility is not born in the United States and does not acquire U.S. citizenship by reason of birth.
(2) The status of diplomatic and consular premises arises from the rules of law relating to immunity from the prescriptive and enforcement jurisdiction of the receiving State; the premises are not part of the territory of the United States of America. (See Restatement (Third) of Foreign Relations Law, Vol. 1, Sec. 466, Comment a and c (1987). See also, Persinger v. Iran, 729 F.2d 835 (D.C. Cir. 1984).
The Canal Zone was a U.S. possession and unincorporated territory that was deemed by the U.S. Supreme Court in the Insular Cases to be outside the jurisdiction of the Constitution’s Article III Federal District Courts, and was instead subject to the Article IV territorial courts. This is why the U.S. Supreme Court and the U.S. State Department state the Canal Zone was not U.S. soil with regard to the establishment of U.S. citizenship, and the unincorporated territory has since been retroceded to the Republic of Panama. This also why the Republic of Panama continued to grant Panamanian citizenship to children born in the Canal Zone while the United States was in possession of the Canal Zone. John McCain was born with the right to claim Panamanian citizenship due to place of birth in addition to naturalized U.S. citizenship by right of blood relationship to two U.S. citizen parents.
