As a concept, foreign policy has been rendered meaningless: the stars finally aligned, Cthulhu now rises to rule the world inclusive.

As the President of the United States, Cthulhu will maintain a base of operations within the former nation, at Washington, DC; the rest of the planet will fall in line under America within the one world government.

To the extent that the cowardly Elder Things, having retreated to their underwater prisons, might constitute splintercells of ideological compatibility, America and the world will have to remain vigilant of oceanic activity. However, as the Elder Things appear functionally to have surrendered, the world should soon remain at peace.
