Demonstrated Destruction Is Deterrence

Chris McInnes

U.S. and Israeli air strikes in the last month underlined the unrivalled ability of sophisticated air forces to reach and destroy sensitive targets.

The devastating attacks contrasted sharply with ineffectual Iranian and Houthi missile and drone attacks. Critically, the demonstrated power of the strikes strengthened deterrence.

Australia should pay attention as it develops strike capabilities for its strategy of deterrence by denial. The key capability implication for the ADF is the centrality of sophisticated air forces in degrading and penetrating air defences and delivering the firepower needed destroy hard targets. The critical policy insight is that a proven ability to destroy sensitive targets at will is a far more compelling deterrent than visions of future capability.

On 27 September Israel killed Hassan Nasrallah, Hezbollah’s secretary-general, as he met with senior Hezbollah leaders in a bunker buried nearly 20 metres under four high-rise buildings in southern Beirut. Israeli aircraft reportedly dropped 80 precision-guided penetrating weapons with 900kg-class warheads. The weapons were dropped at precise angles and the warheads were fuzed to detonate at specific heights to collapse the high-rise buildings and penetrate Nasrallah’s bunker. While there are questions about the strike’s proportionality, its sophistication and effectiveness are unquestioned.
