2. United States and United Kingdom
Though adversaries during the American Revolution and the War of 1812, the US and UK emerged as staunch allies in the 20th century. Their ‘Special Relationship’ was cemented during the World Wars and continues through shared intelligence and cultural ties. The term ‘Special Relationship’ was popularized by British Prime Minister Winston Churchill in a 1946 speech, emphasizing the unique bond between the two nations (instituteforgovernment.org.uk).
