evidence: The issue of the Caribbean islands was handed over to Paolo Di Rosa, at the State Department's legal office for Western Hemisphere affairs. Di Rosa acknowledges only that he has indeed been assigned to handle the matter and that "different islands are in a different status." Asked about Serranilla Bank and Bajo Nuevo, he responds cryptically: "Some of these islands or banks or whatever, we have asserted sovereignty over in various international contexts, even in the face of competing claims from other countries, and we consider our claims superior." He adds, "Some of the islands, we just have no idea where they are; they don't appear on our geographers' maps—we don't know anything about them."
