9.5. 5. In what Manner a Monarchical Government provides for its Security.
A monarchy never destroys itself like a despotic government. But a
kingdom of a moderate extent is liable to sudden invasions: it must
therefore have fortresses to defend its frontiers; and troops to
garrison those fortresses. The least spot of ground is disputed with
military skill and resolution. Despotic states make incursions against
one another; it is monarchies only that wage war.
Fortresses are proper for monarchies; despotic governments are
afraid of them. They dare not entrust their officers with such a
command, as none of them have any affection for the prince or his
government.
