Ahh, the 'cat ate my post earlier. England has only ever been at war with Scotland, Wales, Ireland, France, Spain, Holland, the Vikings and the Normans*. Some of them only once! The civil wars, wars of succession, and various little wars agianst natives don't really count...

*The Romans and Saxons invaded before England really existed, and we only fought the Germans, Italians, Russian, Japan, Iraq, Argintina, Korea Chinese, rebellious Americans, rebellious Boers, various other Indian states and the Austro-Hungarian empire after we became the United Kingdom (1705)

Such a peaceful little country.
