America’s top official in France from 1785-1789, forty-something Thomas Jefferson, came to believe U.S. diplomats should not be overseas more than about eight years at a stretch. He felt if they (and they were then only men) were, they would lose touch with events and opinions at home. As a result, they would eventually be incapable of representing America properly.
He grew concerned also about young men “without attachment” becoming “involved” with European women, and felt their being overseas too long made such “intimacy” almost inevitable. The young women they encountered in diplomatic and social circles (and who, in France and elsewhere on the continent, could speak English) were overwhelmingly aristocrats. He believed “relationships” with those women could damage those “impressionable” young men’s “republican” sentiments and alienate them from the outlooks of most of their fellow Americans at home.
A few years before, a 16 year old future U.S. president became rather “enthralled” by young women he met while visiting Sweden. Yes, it’s a shocker: An American teenage boy loose in Scandinavia notices girls. Yet in that he demonstrated Jefferson’s concerns were perhaps not groundless.
Then lacking the television, internet, etc., that we take for granted, one could see Jefferson’s point about being too far removed from home as well. It took three months minimum for a letter to travel from Europe and to receive a reply from America; and that was usually during the summer months. Far fewer ships risked crossing the Atlantic between December and March – and even navies weren’t keen on it if they could possibly put it off until spring.
