Google Maps: No Roads in Israel?

I’ve been reading some information concerning the fence that was destroyed between the Gaza Strip and Egypt. I wanted to look at a map for an overview.

Where are the roads in Israel? How about the West Bank or Gaza? Go ahead, zoom in, pan around. Nothing is there.

I understand that these maps are not intended to be complete – like those we have in the U.S.A. – but why roads in Lebanon, Syria and Egypt, if none are shown for Israel?
