They might supply high voltage lines, but the transformers to step it down would be local. Blow them up and it would take months to get the juice back on. And it might shut down the water pumping system as well. Just speculatin'.
I can't believe people who don't even have an air force would be so stupid to attack a country that does. But then, they are stupid political tools of izzlam.
A blind mouse would have better luck attacking a hawk.
Sorry, but when terrorists begin to purposely target innocent civilians, they've removed themselves from "civilization," and are no longer privy to the rights or protection of the civilized. What's even worse, we (and the Israeli's) have hamstrung our military by putting what I consider criminal (on the part of politicians) rules of engagement on our military, to the point of telling them they're not allowed to shoot back while under fire! And then prosecuting (persecuting being a better word) our military?
The simple fact is that once Israel stopped brutally pursuing and killing the terrorists, the terrorists saw this as weakness and stepped up their attacks. And during that time, the world decided that it liked Jews a lot better when they were the innocent victims with bodies stacked up like cord wood than people who were willing to defend themselves.
