(IsraelNN.com) According to an Israeli journalist who has published a book abroad, the Jewish State is already engaged in a war with Iran.

For the past two and a half years, says Ronen Bergman, Israel has been fighting a quiet undercover war with the Islamic Republic through computer technology, espionage, selective assassination there, and a little help from its friends.

Military censorship in Israel has prevented the publication of much of the material, according to a review of his book, “The Secret War with Iran,” published Monday in The New York Sun daily newspaper.

But Bergman noted that Iranian work on nuclear technology had been stymied by Israeli operatives long before efforts toward that goal were being reported in the Israeli media.

Moreover, he wrote, a highly-placed Iranian military official defected to the United States in February 2007 and began helping in the war against the Islamic Republic.

Hizbullah Part of the Picture

Bergman also wrote about the assassination in February 2008 of Imad Mughniyeh, then second-in-command of the Hizbullah terrorist organization.

With international speculation rampant as to the identity of the operatives who carried out the professional hit, Bergman stops just short of laying the blame for the execution at Israel’s doorstep.

Hizbullah still holds the Jewish State responsible, and has vowed revenge. In this regard, numerous concrete terror warnings abound for Israelis abroad at present, particularly due to the holiday season.

Travelers are being warned to take extra precautions, and Israelis have been ordered to stay away from the Sinai Peninsula at all costs. Those who have ignored the warnings and have traveled there have been told to leave immediately due to the high risk of being kidnapped by terrorists.
