power and authority. Then, with his own strength and their
support, he can easily undermine the more powerful neigh-
bours and hence dominate the region. However, an invader
who fails to manage relations with his new neighbours will
soon lose what territory he has taken; and even while he’s
still holding on to it, he’ll be up against all kinds of trouble
and hostility.
The Romans followed these principles whenever they took
a new province: they sent colonists; they established friendly
relations with weaker neighbours, though without allowing
them to increase their power; they undermined stronger neigh-
bours and they prevented powerful rulers outside the region
from gaining influence there. Their handling of Greece will
be example enough: they established good relations with the
Achaeans and the Aetolians; Macedonia’s power was under-
mined; they drove out Antiochus. They didn’t reward the
good behaviour of the Achaeans and the Aetolians by
allowing them any new territory and whenever Philip con-
vinced them to establish friendly relations with him they made
sure he was weakened as a result. Antiochus, for all his
strength, was never allowed any influence in the region. The
Romans were simply doing what all wise rulers must: not
restricting themselves to dealing with present threats but using
every means at their disposal to foresee and forestall future
problems as well. Seen in advance, trouble is easily dealt with;
wait until it’s on top of you and your reaction will come too
late, the malaise is already irreversible.
Remember what the doctors tell us about tuberculosis: in
its early stages it’s easy to cure and hard to diagnose, but if
you don’t spot it and treat it, as time goes by it gets easy to
diagnose and hard to cure. So it is with affairs of state. See
trouble in advance (but you have to be shrewd) and you can
clear it up quickly. Miss it, and by the time it’s big enough
for everyone to see it will be too late to do anything about it.
However, since they had this capacity for seeing a threat in
