An Iranian retaliation to a military strike on its nuclear sites will likely be
limited, and significantly smaller in scope than commonly believed in the West,
a new study published by the head of the Institute for National Security Studies
(INSS), Maj.-Gen. (res.) Amos Yadlin, said on Wednesday.

assessed the likely Iranian strategic calculations when choosing a

Iran’s main retaliatory strike force is composed of 300-400
surface-to-surface missiles, made up of the Shihab 3 with a range of 1,300 km.,
and the Ghadir with a range of over 1,600 km., the authors wrote.
of these missiles do not have high accuracy and do not allow for the pinpoint
striking of a target,” the paper said.
The Shihab’s Circular Error
Probable (CEP), indicating its accuracy, is over two kilometers, and the
Ghadir’s CEP is hundreds of meters.
A Shihab can carry a one-ton warhead
of conventional explosives, and the Ghadir can carry 750 kg.
strikes can be used to terrorize cities, rather than hitting targets accurately,
Yadlin and Golov said.
Actual damage can be contained to a minimum,
through early warning alerts for civilians, an efficient use of the Arrow 2
anti-missile shield, and an improvement in projectile defense fortifications for
the general population.
Although suspicions exist that Iran can arm its
missiles with chemical and biological warheads, their low accuracy and
ineffectiveness as unconventional delivery systems, combined with Iran’s
understanding that such a move will provoke a massive military response, will
prevent such a scenario, said the authors.
An additional threat exists in
the form of Iran’s extraterritorial terrorism capabilities, embodied by the
IRGC’s Quds Force.
Past Quds Force attempts to carry out attacks in
revenge for covert strikes on the Iranian nuclear program show the limitations
of this apparatus, the study said.
“These [Iranian] efforts failed and
they point to a limited Iranian ability to carry out wide-scale terror attacks,
and to a good ability to foil them in the Western world,” the authors stated,
before concluding that this threat can be contained.
threats include Iran’s air force and fleet of drones.
Iran’s fighter jets
are inferior to those of Israel, which enjoys two layers of air defenses against
hostile intrusions: Interception aircraft and a chain of anti-aircraft weapon
Iran’s most advanced jets, the Sukhoi 24, cannot get to Israel
and back without midair refueling and would be vulnerable to air defense
Iran’s drones are also primitive in comparison with their Western
counterparts, “and do not allow much operational flexibility after their
launch,” the study said.
The most realistic UAV threat consists of
“suicide drones from Lebanon or Syria” that could be deployed, and this scenario
merits preparations, but is “not the kind of threat that Israel can’t absorb,”
the paper continued.
Iran’s long-range naval strike capabilities are
“very limited,” the paper said, and consists mainly of Soviet-made submarines
that operate in the Persian Gulf and Indian Ocean.
Ships that can reach
Israeli shores would have a hard time crossing the Suez Canal during a conflict,
and would likely run into Israel Navy ships armed with advanced sea-to-sea
An attack boat disguised as a civilian vessel might be used to
launch sea-to-shore missiles and mini suicide submarines could be deployed,
though this threat can be countered by Israel as well, according to the
There is no Iranian ground force option to speak of, due to the
1,200 km. distance between the two countries, Yadlin and Golov
Iran’s capabilities are far from “Gog and Magog” scenarios and are
limited to missile strikes and terror attacks, the effects of which will be
principally psychological, they wrote.
If an initial attack on Iran is
surgical and aimed only at nuclear sites, Iran, when weighing responses will

Similarly, Tehran will likely seek to avoid provoking a large-scale
second Israeli wave of attacks that could be used to cause more damage to
nuclear sites, as well as targeting regime assets.
Yadlin and Golov set
out a scale of five possible Iranian responses, ranging from total restraint to
a regional escalation.
One highly likely Iranian response is a “tit for
tat” strategy, targeting Israeli nuclear reactors, they said.
scenario would see “a significant number of missiles fired from Iran and Lebanon
towards Dimona or any other target perceived as being ‘nuclear-associated’ in
Israel, in order to send a message of parity between Iran and Israel, and maybe
even strike the Israeli facilities.”
“There’s a high chance that this
method of operation will be included in the Iranian response, as a wider
response, or a limited Iranian response,” the authors
Alternatively, Iran could widen its response and include the
activation of terrorism cells, while also firing off one or two missile barrages
at Israeli cities, and target Saudi and Western targets in the

believe that the chances of such an Iranian response is high if a Western attack
hits Iranian nuclear infrastructure but does not harm other regime assets,” the
Such a response would enable Iran to balance out its need to
reply to an attack, but avoid an escalation that will threaten regime assets not
directly tied to the military nuclear project.
A more serious yet less
likely potential response, according to the study, would be sparked by an
Iranian desire to avenge its national honor, punish Israel and isolate it from
This would entail a massive launch of dozens of missiles at
Israeli cities a day, paralyzing civilian life, and enlarging the psychological
pressure against the Israeli population.
In this option, “The Iranians
will try to achieve maximum deterrence against the Israeli government in a
We assess that the regime in Tehran assumes that such a
response will provoke a significant Israeli response, that could lead to an
escalation in the conflict between the two countries.
“This could enable
an additional strike at nuclear infrastructure, and a large-scale strike of
Iranian economic interests and regime assets.
This escalation could spin
out of control and encourage US military involvement, which would threaten the
survivability of the regime of the Ayatollahs.
As a result, we assess
that the Iranian regime will refrain from such a response against Israel, so
long as the Western attack focuses on nuclear infrastructure,” Yadlin and Golov
Finally, Iran could go for a maximal response aimed at regional
escalation, attacking the US, Gulf states and Israel.
necessitate a US response, and Iran would only pursue this course if it does not
fear a significant attack on its regime assets, since it would already have
sensed its survival to be in jeopardy.
In such an extreme scenario Iran
would try to “set alight the region” and hope for Russia to achieve a
cease-fire, before sustaining more damage.
The study concluded that such
a retaliation is unlikely.
In examining potential responses by Iran’s
proxies and allies, the authors noted that Hezbollah’s rocket arsenal has grown
significantly since the Second Lebanon War of 2006, but added that Israel’s
defensive, offensive, and intelligence capabilities have increased significantly
Hezbollah is fighting for the Assad regime in Syria, and it
remains unclear how this erosion on its capabilities will influence its
readiness for a confrontation with Israel, Yadlin and Golov

Syria’s rocket and missile arsenal poses a strategic threat to
Israel, but Syria is not an Iranian proxy and acts according to its own
interests, the paper said.
The civil war has greatly reduced Assad’s
willingness to take part in an Iranian response against Israel, although growing
dependence on the Iranian patron and Assad’s wish to revenge attacks attributed
to Israel could allow for a small response.
“Even if Assad responds, it
will be symbolic and minimal, such as letting terrorists launch attacks from
Syria, and this won’t drag Israel into full-scale war,” they said.
