US foreign policy and the pragmatic use of international institutions

The use of international institutions by the United States is characterised by pragmatism. US officials approach institutions as instruments of convenience across time, across regions, and across economic and security issues. US political rhetoric since the end of World War II has emphasised the importance of multilateralism. But in practice, the US approach reflects a process of trial and error and a tendency to focus on what works in terms of US domestic and foreign policy interests. Successive US administrations have proved flexible in modifying, expanding, neglecting and even discarding those institutions whose initial instrumental purpose is no longer essential. These twists and turns have proved frustrating to America's economic and security allies who have been forced to bear the brunt of adjusting to the changing institutional preferences of their more powerful partner.
