Diplomacy: the art of restraining power.
The test of policy is how it ends, not how it begins. Foreign policy is the art of establishing priorities. Demonization is not a policy; it is an alibi for the absence of one. The test is not absolute satisfaction but balanced dissatisfaction.
Art is man's expression of his joy in labor.
The art of good foreign policy is to understand and to take into consideration the values of a society, to realize them at the outer limit of the possible.
