evidence: But the State Department is a huge and labyrinthine organization, and finding someone there who has answers to offer—let alone getting that someone to actually offer them—is a tricky process. Marx sent his inquiries to William B. Wood, who heads the department's Office of the Geographer and Global Issues. Wood passed them on to a staffer, Leo Dillon, who is quick to state that he cannot state very much. "Our office can only confirm that according to our records, the U.S. has no claims to any of those islands," Dillon says. Besides, he adds, "the guano has been taken from those islands," although he then admits he's not sure that's actually true. However, he does acknowledge that there are two Caribbean islands—Serranilla Bank and Bajo Nuevo—to which the United States has not repudiated its claim, even though other countries claim them as well. But he considers Olson's other arguments ludicrous; and anyway, Dillon says, "we deal with sovereignty from the current, not the historical, perspective." These were questions for the State Department's legal division, and he has already forwarded Marx's inquiries to that office.
