Are you honest, Max? Does the continental United States now embrace Buenos Aires, as well as Vancouver?
While we're on the subject of land masses. Several years ago, Japan attempted to establish a 200 mile limit around two small artificial islands which it had built in rich Pacific fishing grounds and over which it declared sovereignty. The islands were about the size of bed springs, and there was some question whether they were large enough to qualify. In the end, as I remember, the effort failed because international law doesn't recognize artificial islands for this purpose.
