Since yesterday I'm in the mood to try my skill at the greatest challenge in deterrence & defence on this planet; how would Iran deter its (potential) enemies and defend itself in case this fails?
Iran is playing regional power out of an underdog position. It's a large and populous country in its region, but its list of potential enemies is peerless:
- Saudi-Arabia
- Kuwait
- UAE
- Qatar
- Bahrain
- Oman (not sure)
- Pakistan
- Turkey
- Israel
- U.S.
- Russia
- Afghanistan/Taliban
 |
This map shows only the two biggest religious groups.
There are eight more substantial religious groups in Iran! |
(The second map is from 1964.)
The biggest relief from the long list of potential enemies with no real ally in sight is that many potential aggressors have no interest in unleashing civil war chaos by breaking the Iranian state, so presumably they won't do it unless their leadership is idiotic or super ignorant *sigh*.
Now, let's group the potential threats:
Air raid threat
- U.S. (cruise missile diplomacy)
- Israel
Air war and naval blockade threat from the South
- Saudi Arabia
- UAE
- Kuwait
- Qatar
- Bahrain
- Oman
- U.S.
Insurrection threat
- almost all domestic groups except very devout Shia Persians and beneficiaries of status quo
- U.S. (possible foreign sponsor)
- all Persian Gulf pseudomonarchic kleptocracies (possible foreign sponsors)
Civil War spillover effects
- Afghanistan (Taliban/Pashtu)
- Iraq (Sunni insurgencies)
- Kurds (from Iraq, Turkey)
- Pakistan (if the Balochi rise up there for real first)
Distant scenarios
- Russia (realistic only once quasi-imperial control of Caucasus region was regained)
- Turkey (if Turkey becomes great power ~ Ottoman Empire again)
Full scale invasion threat
- international coalition (only if they are really mad)
So far this still served its purpose, though the air war inferiority across the Persian Gulf is no doubt unsatisfactory to the Iranian government. One should also keep in mind that the armed forces of such a state need not only serve legitimate purposes, but are also tasked more or less (varying by agency) with perpetuating the current political system (a theocracy with lots of democratic elements that are limited in their reform ability).
Again; even countries like North Korea, Russia or even Jordan have a simpler security environment!
Well, what would I recommend?
Air raid threat
This cannot really be protected against, for strategic and tactical surprise has to be expected and attackers would likely use the best equipment available to them. To go underground with the most likely targets is very expensive, and rather not feasible for many such targets (particularly the national government).
Air War and naval blockade threat
Iran's most important harbours are deep in the Persian Gulf. It's unrealistic to hope for the ability to export oil from there to world markets with less than about € 20 bn military spending for this air/sea war defence capability alone, and that's before taking into account a possible arms race with Saudi Arabia.
The threat of a protracted air war is a little different. The hostiles' air bases would mostly be in missile range (Iskander etc), so Iran wouldn't need to gain air superiority in the air or buy many expensive air defence systems. It could send an aircraft on a high altitude high speed run to quickly make some synthetic aperture radar imagery from afar, transmit the data to a ground station where officers decide which coordinates to shoot at with accurate missiles within minutes. The small combat aircraft inventories of Kuwait, UAE, Oman, Qatar and Bahrain could be defeated this way. Saudi Arabia's air power is in a different league, of course.
The best defence might be a surprisingly cheap strategy; the less offensive air power potential Iran has, the less motivated the Southern neighbours might be to build up their own air power. This isn't reliable (who knows what the kleptocracies build up their mini air forces for at all?), of course.
A promising route might be to build a respected air defence cluster at Tehran (S-300 and short range SAMs, meant to limit the damage done in an air war), pursue some ballistic PGMs (instead of inaccurate 1980's style "
War of the Cities" rockets) and once possible get some 40ish Su-3x fighters or Chinese equivalents* with air combat munitions only (but also SAR and datalink capability).
There's little point in trying to use anything of lesser quality (older SAMs, inaccurate rockets or worse fighters), for it would fail to deter and fail to defend unless procured and operated in uneconomical quantities.
Insurrection threat
The best way to address this threat would no doubt be to treat minorities well, and to ensure loyalty of the armed services (to the government). There is likely a tipping point of damage to the state and insurrection activity that would lead to multiple more groups rising up, so even though or if minor insurgencies may be unavoidable (or couldn't be ended, as in Balochistan) at least that tipping point needs to be avoided.
It makes sense to prefer Shia Persians for key positions in the armed forces, and even for basic training. The less military and paramilitary competence is available to potentially revolting minorities the less likely is their revolt (well, that's what I suppose). Munitions depots need to be guarded and locked up well, and the vast majority of munitions should be stored in territories that would rather not revolt (Shia Persians areas). Certain very reliable units need be positioned at or near Tehran, and be suitable to secure the capital and especially government organs. Western countries need such protection against airborne raids only, but governments such as the Iranian one also need to have domestic revolt in mind.
Low level uprisings should be countered with policing, with military forces in the region but only held in reserve as quick reaction force to back up the police forces. Police can investigate well with the training and equipment required. Intelligence service-like methods of intelligence gathering on (violent) opposition groups and their supporters without link to specific crimes need to be part of the repertoire, but preferably so in separate police units (not the investigating ones). Foreign sponsorship of insurrection or terrorism would need to be detected, investigated, understood, proved, potentially interdicted and then exposed.
Civil War spillover effects
This includes all measures from dealing with the insurrection threat plus no provision of safe harbours (no toleration of recruiting, fundraising, arms purchases) for foreign civil war factions and a lot more military presence. Refugee camps would be operated by the Red Crescent or whatever humanitarian NGO is available to do it, but these camps would need to be policed with proper identity checks and documentation of at least all male refugees. Ideally the camps would be created at some place where public construction projects provide employment opportunity for most adult male refugees. Lots of military-secured road police checkpoints, surveillance between roads by military-reinforced police or border guards and other visible measures would be taken to keep the peace on the Iranian side of the border. Border transgressions by armed forces would be dealt with by making an example on the first occasion; excessive firepower involving artillery fire should communicate a zero tolerance attitude towards armed border transgressions.
Distant scenarios
Back in the Shah's days Russia was kept out by buying large amounts of sophisticated weapon systems (F-14, F-4, F-5, tanks) from the U.S.. This was in part an effort to actually possess a conventional warfare capability and in part a signal of bloc membership; the latter was probably a better deterrent in combination with the ethnic and religious composition that would have made a forced "communist" takeover a worse quagmire than Afghanistan would become after 1979.
Russia might be deterred like this again in the long term, though cooperation (in regard to oil industry, arms purchases and even a real alliance) seems more achievable than getting a Western big brother to deter a schoolyard bully.
Long-term conflict with Turkey could not be deterred this way, for it would more likely than not be about the Kurds. Turkey has made military incursions into Iraq and Syria without those governments' public approval or even against their public disapproval. These incursions were mostly aimed at harming Kurdish separatist forces. The Kurdish successes in Northern Syria and the Kurdish proto-state in Northern Iraq may lead to a declaration of Kurdish independence, which might lead to all out war with Turkey. This might involve Iran with its sizeable Turkish minority in its Northwest, and might so at a scale that would be ill-described with a mere "civil war spillover". I suppose the ability to make a stand at the border with conventional forces would be required to protect Iranian sovereignty in such a case, regardless of how Iran deals with the Kurds itself.
Full scale invasion threat
This cannot be defended against, but it can be deterred. The public of the potential aggressor countries in question could be informed about Iranian ethnic and religious diversity and fracture lines. The risk of causing civil war and breeding ground for extremism that would last for decades should be too great for any invader coalition. This can be reinforced by ensuring that enough Iranians (Shia Persians) are trained as light infantry, and by a promise to open the arms and munitions depots in time to arm the people for a powerful insurgency against any occupation force.
Now, what forces would be advisable?
- Border guards with light arms (up to recoilless guns and mortars) and decent equipment for surveillance as well as sufficient border policing skills.
- An air force of 40+ Su-3x fighters, hundreds of ballistic PGMs (300-499 km range, warhead effective against hardened aircraft shelter), ground radar stations that could support the Su-3x, 20+ ground attack aircraft for counter insurgency (Su-25) and maybe two regiments of S-300 at Tehran supported by additional low level air defences.
- An army of maybe six mechanised brigades and ten small infantry-heavy brigades.
- A kind of national guard (not the current Basij or Islamic Revolutionary Guards) that ensures enough males of loyal demographics are equipped and qualified as light infantrymen and NCOs. This would help deter invasion and provide a foundation for a quick expansion of the regular army. These forces would -when mobilised- also allow the regular army to be massed in one region if necessary, taking over its security missions elsewhere.
Furthermore, an alliance either with Russia (in the medium term) or India (in the long term, particularly if Russia doesn't agree) would make much sense. An alliance with Shia-dominated Iraq should be self-evident and might - if approached with great skill and care - even create an open door to the West if and when Western leaders are not too close-minded.
The current Iranian policy of playing protector and supporter for more or less oppressed Shia abroad does more harm than good for Iran, in particular it ensures the hostility of the Persian Gulf kleptocrat states and provides excuses for Israeli and U.S. political hostility.
The old and by now obviously given-up strategy of deterrence though being close to becoming a nuclear power (essentially enriching Uranium more than needed for civilian energy purposes, but less than needed for fission warheads) should not be revived. The
Iran nuclear deal framework is a huge success for everyone except the fearmongers and warmongers in the U.S. whose plans it sabotages.
The one thing that Iran needs to guard itself against the most are great power ambitions. Those can only cause trouble given the hardly permissive international environment. Great power ambitions would also be very expensive, and Iran has great need for investment in domestic economic development instead. It is also extremely wasteful to purchase and maintain capabilities that would not be critical to deterrence or defence success, such as old fighters or rather pointless naval forces. Unnecessary offensive systems are an even greater waste of resources, for they provoke additional political hostility and arms racing.
Last but not least; Iran needs to work for a better opinion of it in the Western world, or at least in Europe. Substantial domestic improvements (such as an end to the de facto Apartheid against the Bahá'í minority and some more womens' rights) and no more stupid sabre rattling would create a fertile soil for a ten-year image improvement campaign.
