"Iron Wall" indeed. This is the Israeli way of referring to the ideological founder of 'Revisionist Zionism', Vladimir Jabotinsky, the fascist-like founder of Ariel Sharon's political party and ideological convictions.
Israel Prepares for Iraq War - 'Iron Wall' To Be Alert Code in Event of
Report by Yo'av Limor - Ma'ariv July 30, 2002 [FBIS Translated Text]
"Homat Barzel" [Iron Wall] -- this will be the alert code to be used by the
IDF Home Front Command to warn the population of a missile attack on Israel.
The IDF has recently stepped up the preparation of the home front in
anticipation of the expected US attack on Iraq. Security officials
estimate that Saddam Husayn will order his army to fire long-range missiles
at Israel, including some outfitted with chemical and biological warheads,
already at the beginning of the US strike.
In "quiet contacts" held recently with the heads of the US Administration,
Israel asked a forewarning of several days prior to the strike to be able to
prepare for the possibility of missiles being fired on Israel's civilian
population. The issue was raised by the prime minister, the defense
minister, and the chief of staff in their visits to Washington.
Sources in Israel affirmed that a forewarning of a mere several hours --as
prior to the US attack on Afghanistan -- would be insufficient. The IDF
foresees a public "avalanche" on the gas mask distribution centers in case
of an emergency. Therefore, it has trained some 3,000 reservists, who would
be called up at once to help the centers increase distribution to over
50,000 gas masks a day.
The IDF has also finished drafting the procedures for updating and informing
the public. The moment the report is received of a missile having been
fired, a siren will be activated throughout the country, broadcasts on all
television and radio stations will stop, and the public will be notified of
the new alert code (replacing "Nahash Tzefa" of Gulf War fame), which will
be read out by Oded Ben-Ami, a former IDF spokesman.
