    The assignment is designed so that aggregation may occur during the
    normal operation of the routing algorithms.  Viewed from France, the
    cluster may not aggregate at all, since Guernsey and Jersey are closer
    to France.  But viewed from Germany, it is extremely likely to
    aggregate; from China, almost certain.

It amuses me greatly that there's anyone who still seriously
believes that network topology, and geography, are even remotely
related when it comes to international connections.

It may seem that way in Europe, at the minute, but that's
largely the result of the EEC attempting to make the connections
inside Europe stop being international (or that's how it seems
from here) - it certainly wasn't that way a shortish while ago.

Another area about the same size as Europe contains Libya,
Egypt, Israel, Lebanon, Syria, Jordan, Iraq, Iran, and Kuwait.

Does anyone really believe that routes from that area will
form any kind of aggregation anytime in the forseeable future?

Or to take a current obvious example, just look at the Malaysian
pensinula - excluding Burma (Myramar (sp?)) as they're not
connected at all, and so no-one has any idea what will happen
with them.  But Thailand, Malaysia, and Singapore all have
internet connections, none are connected to any of the others,
and what's more, their internet connectins all connect to the
rest of the internet at widely dispersed locations (two at
various places on the east cost side of the US, and one on the
west coast).   Last I heard, Japan as a single country couldn't
even manage to present a unified routing interface to the
rest of the world.

International links are composed almost entirely out of politics,
often expressed in the form of tarrifs set by various
tellecommunication authorities, and proximity is rarely any
kind of indicationas to what makes sense, financially, or
politically in other eays.
