I will just go back to the first point you made. Our F-18s are absolutely safe and viable. That's why government spent billions of dollars on the upgrade. The airplanes will fly. When they fly they will be at their best capacity. The issue is, as everybody understands, that as airplanes age, the required maintenance goes up.
When they do fly they will be effective, as we saw in Libya.
What the Israelis are doing is this. Again, because different fleets have different ages, they have to continue investing in their current fleets, and they also have a mixture of capability, given, as you point out, the environment they live in. They have to have a range of options available to them, so the government can defend themselves as best they can. Therefore, they make a slightly different decision from what we may make, based on our circumstances.
