Here is a clue. Moshe Arens and Israel Harel will not have their articles featured in a left wing media outlet. Haaretz is certerist. Right wing supporters of Israel are so used to their right wing rags in which every article varies from right wing to extreme right wing, that they think that any media that has any left wing content at all must be left wing. The fact is that "cyber terrorism" has much in common with ordinary terrorism. They will strike where they can make the biggest splash. Haaretz has a much higher international profile than any of Israel's home grown right wing rags.
