At
sea, swarms of IRGC speed boats and jet skis pose a threat to shipping
in the Gulf if nobody is engaging them, but their asymmetric advantage
disappears when a shooting war starts. The peculiarly accident-prone
Iranian Navy, which has lost three major vessels to accidents and
mishaps in the last three years, might have some surprises in store,
particularly in the form of their missile-capable light submarine fleet,
but in a conventional war this threat would be eliminated rapidly.
On land, Iran’s ground forces are numerically far superior to those
of the GCC combined, but if a ground war every developed, difficult to
conceive of in current circumstances, then it comes with the risk that
regime cohesion will be threatened, with rebellious provinces such as
Khuzestan, Sistan Baluchistan and the Kurdish North West which can be
kept in check in peacetime likely to take advantage of the chaos.
Finally, Iran’s ballistic missile fleet and drones: substantial and
well-protected, if ever Iran chose to use this capability en masse,
then it would need to penetrate Saudi Arabia’s anti-ballistic shield –
the most practiced such capability in the world - as well as withstand
counter attack by Saudi Arabia’s own very substantial fleet of Chinese
DF-3 (CSS-2), DF-21s (CSS-5), and probably a third as yet unidentified
system. Nor could Iranian use of their ballistic missile capability
escape drawing into the conflict the United States, with its capability
both to detect and destroy even the deepest underground facilities.
So on balance, while Iran’s use of asymmetric warfare techniques and
its Forward Defence strategy works well in less-than-open-warfare
scenarios, should a conventional war break out then the balance of
advantage switches dramatically. The Iranian negotiators have every
reason therefore to try and maintain the existing status quo, in the
limited circumstances of which they enjoy the advantage.
Similar calculations are also likely to have been made in Abu Dhabi
and Riyadh, where there is much talk of late about de-escalating
tensions with Iran. But such de-escalation has not as yet involved any
sacrifice of major interests, and indeed in Yemen Saudi Arabia has
become more explicit recently in its targeting of what it describes as
IRGC facilities. In the meantime, the United Arab Emirates in
particular is stepping up its conventional warfare capability, to match
and to complement that of Saudi Arabia. The equipment on the UAE’s
shopping list – Rafale, F-35s, MQ-9B Reaper drones and EA-18G Growler
electronic counter measures aircraft – are just what one would need to
conduct offensive operations over Iran, without necessarily any overt
dependency on the Americans.
A successful outcome in Vienna may therefore postpone a potential
nuclear Armageddon, but will still leave the Gulf with an intractable
security problem – unless wider regional issues and ambitions can also
be reconciled through diplomacy.
