Reciprocity
There are streets in Paris commemorating Benjamin Franklin, George Washington, Woodrow Wilson, Franklin Roosevelt and John F. Kennedy.
There are no corresponding streets in Washington D.C., for all that it was designed by a French urbanist, apart from Lafayette Square (it really should be de la Fayette Square). Rochambeau is ignored. Not remembered at all is the man who did the most for the American revolution, and arguably paid for it with his life, Louis XVI.
