ACCEPTABILITY.
Since the principal purpose in sending ambassadors is to secure peace by cultivating friendly relations with other governments, it is evidently wise before making an appointment to any country to learn whether the person whom it is expected to send is acceptable to that country. Accordingly it is customary before making the appointment public to make the nomination privately to the foreign government and to express the hope that it will be found acceptable. Even the nominee knows nothing of it, and is thus saved the pain of rejection in case that should occur. If there is no personal objection to the nominee, and if there is no doubt that his country possesses full sovereignty and is therefore entitled to send ambassadors, his government is notified of the fact that he is acceptable; but should there be any objection to him—and sometimes very trifling ones will suffice—his government is notified that he is persona non grata (not an agreeable person), and it proceeds to make other nominations. Not only has the foreign government the right to reject a nominee but also to demand his recall at any time if there is any well grounded dissatisfaction with him. One American ambassador was recalled because complaint was made about his bad manners.
