Opinion | National security elite ignore needs of the people at their own peril
- When leaders become predatory through corruption and infighting, their empire or civilisation risks falling through a combination of internal collapse and foreign invasion
- Today, elite interests are increasingly out of touch with those of the masses, who want peace, stability, better jobs and healthcare, leading to a loss of public trust

Gibbon attributed the Roman fall to four principal causes, which persisted across more than 1,000 years: the “injuries of time and nature”; the hostile attacks of the Barbarians and the Christians; the use and abuse of materials; and, the domestic quarrels of the Romans. His warnings apply even today, even though he was reminding the rising British elite what to look out for in their bid for empire.
The Roman empire rose as the effectiveness of Roman military discipline and organisation overwhelmed all enemies. The Praetorian Guard was the core staff between the consul and his legions. They also operated as the intelligence arm of the empire, involved in strategy, logistics, information couriers and diplomacy with allies and enemies alike.
Within Rome, as the elite charged with defending the capital, the Praetorian Guard later became kingmakers since weak emperors needed to have the military on their side. They took part in the assassination of at least one emperor and helped put several others on the throne.
