The
Special Relationship is a phrase used to describe the exceptionally close political, diplomatic, cultural, economic, military and historical relations between the
United Kingdom and the
United States following its use in a 1946 speech by British
statesman Winston Churchill. Although both the United Kingdom and United States have close relationships with many other nations, the level of cooperation between them in economic activity, trade and commerce, military planning, execution of military operations, nuclear weapons technology, and intelligence sharing has been described as "unparalleled" among
major powers.
