IN the current conflict in Gaza, casualty figures play a big role in the minds of uninvolved observers.
When they hear that no Israelis have been killed by missiles fired from Gaza, but that 100 Gazans have been killed by Israeli counter-strikes, people tend to sympathise with the side with the larger body count. But that is simplistic.
There have been no deaths in Israel because the majority of the missiles targeted at populated areas have been intercepted by the Iron Dome anti-missile system. This has been developed by Israel at great expense precisely to protect its civilian population from such repeated attacks.
