From an interview with Israeli military expert Martin Van Creveld:
There seems to be a fear about a large scale conflict; militarily, what do you think that Israel could put in place?
With its vital infrastructure—power plants, fuel depots, factories, and the like—exposed to precision-guided missiles launched by Hezbolla Syria and possibly Iran, Israel will find itself in a difficult situation. As well as doing its best to protect these assets by means of its highly-developed surface-to air missile system, it will mount air- and missile attacks on enemy air defenses, missile launching sites, and infrastructure targets (one Israeli officer has recently warned that, should Hezbollah get involve in a war with Israel, the latter would bomb Lebanon back into the Stone Age). One can also expect Israeli commando raids against military targets which, for one reason or another, cannot be tackled by airpower on its own.
