Many countries dislike each other simply because of neighboring borders.
Canada and America seem to share a mutual dislike for each other for no
particular reason apart from the fact that they share a border. The same
could be said for Australia and New Zealand; they have never had a notable
conflict but thanks to their geographical proximity they have always shared
a fierce rivalry.
The state of affairs between England and France is something more than
dislike, slightly stronger than a rivalry. They don’t even share a border. 26
