Anglophile
An Anglophile is someone who loves England and appreciates its historical significance.
An Anglophile, for example, might insist that William Shakespeare was the most influential person of the second millennium.
An Anglophile might also admire the way the British stood alone against Nazi tyranny for two years, invented concepts such as the rule of law and freedom of speech, and have devised a tolerant society where people are judged on their merits not their color or religion.
An Anglophile might also recognize the contributions that Britain has made to science and literature far out of proportion to the size of its population.
As a citizen of the USA, an Anglophile would salute the British for standing shoulder-to-shoulder with the United States for 65 years since World War 2.
