On defensive power

.
People seek security in an uncertain, not exactly safe world. The consequences can be self-defeating.

One such example is an arms race. One state is a bit superior to his neighbour - the neighbour can't stand it and strives for superiority as well. Thus they spiral into an arms race, in worst case till they go beyond the sustainable strength. Inevitably one power realises that its strength isn't sustainable - but probably doesn't dare to accept inferiority. The result may be a war - the attempt to exploit a fleeting moment of unsustainable superiority that promises a better end than inferiority.
The situation in 1912-1914 and especially after the first mobilizations in 1914 was similar.

A theoretical way out is to build up military strength that's not of use in strategic offence. This way one power could be at strength "200" if defending itself and "100" if it's an aggressor - with a similar neighbour. Neither power would need to fear inferiority in war and no arms race would be necessary to feel safe.

Fortifications used to provide exactly this; military utility in strategic defence that's not directly useful for strategic offence. Permanent fortifications have lost their strategic utility, though. Even the fortifications along the Korean border don't come close.
Medieval fortresses are popular among tourists and generally capture the attention and imagination of people. These visitors don't reall understand how bad it really was when fortifications lost their strategic relevance.

There's a general problem on the tactical level that makes it difficult to buy exclusively "defensive" weapons (even anti-tank missiles have offensive uses!) for modern ground warfare: Operational defence neccessitates offensive actions on the tactical level. In fact, even stationary defensive concepts don't work without tactical counter-attacks.
Battlefield air defences are probably the only exclusively defensive combat component of ground forces and even they are of greater use during mobile (potentially offensive) operations than during static phases (= never offensive).

A competent operational defence with mobile forces is usually offensive on the tactical level, too: It's mostly about giving some ground in exchange for a good opportunity to counter-attack.

The power of mobile combined arms operations disqualifies the concept of "slow" (and therefore not much "offensive") ground forces such as infantry-centric forces. A total defence concept is not worth its budget if it cannot withstand a smaller and balanced offensive concept.

Finally, strategic defence is rarely exclusively defensive and successful at once. Successful examples that came close to total defence depended very much on geographic obstacles.

For clarification; defence is supposed to be the superior form of combat on the tactical level, but only with an at least similar degree of combat readiness. Real warfare tends to be tricky in this regard.
Defence is strong, but it's not decisive. History knows many example of two forces of about equal total strength clashing and the defensive one lost. This tragedy has hit many army commanders on the field of battle and modern European warfare had also several extremely impressive examples.

The only realm where a total defence concept seems to have the potential of success is the political level. The invention of defensive alliances (where members are not supposed to support an aggression of an ally) was ground-breaking.

The Cold War has taught us that this doesn't suffice to avert wasteful arms races. The problem was that NATO was perceived as one bloc by the Kremlin.
The Kremlin did indeed believe that all important NATO members would participate in a hypothetical aggression, even though they would not have been legally obliged to.

The post-Cold War NATO shows an even worse side-effect: Bored by the peace and relative lack of tensions among members, their attention became focused outward on minimal to ridiculously marginal problems. The defensive alliance became quite extrovert and asserted the right to keep the neighbourhood (not jsut its members) safe.

A focus on tactical to strategic defence was and is enticing for national security planners who want to make do with an affordable or even small budget. Sadly, there doesn't seem to be the right technology to make it work.

The good thing about all this is of course that we Europeans are productive enough to afford a degree of military superiority over our neighbours that discourages even the attempt of an arms race against us. This strategy for preserving peace and providing security does of course only work if your power/alliance can sustain a vastly greater military might.

Asia might not be able to rely on this concept. It might instead depend on geographical barriers (Himalaya, Pacific Ocean). The defensive alliance concept could help Asia as well - but they should avoid NATO's mistake and not appear too united. That is of course one of my rather "twisted" ideas and extremely unlikely to ever gain much ground among pundits ...


Finally, one more remark: The invention of "how to build a defensive army" - be it hardware, tactic or operational art - such an invention would be worthy of a Nobel Peace Prize and easily the greatest thing of the century.

  1. Having a lot of nukes stops all aggressive steps of your enemies.

    After stoping nations to intimitate you, you should prepare against assymmetric threats like suiciders, dirty bombs, terror rocketing and cyber attacks.

    Therefore you need a integrated security system with all branches involved.

  2. Nukes are not an option for every state.
    I don't trust as much in nukes as you do anyway;

  3. I dont know a great deal about Eurpean warfare before castles were irrelevented, but certainly in the UK, their main use was that they could shelter an aggressive force.
    An invading army either had to reduce your border forts and destroy the forces they sheltered, or the army inside would follow on behind the invader and savage his supply trains.
    But equaly, the forces in the border forts could cross the border and raid settlements.

    The Norman Castles were manned almost exclusivly by Cavalry for both purposes.

    I think realisticly you need Geography, or planet shaping engineering projects.
    The English Channel is a two way defence barrier, its just been the relative Naval Superiority of the UK thats rendered it a one way wall.
    If we brought our army home and destroyed our transports, we'd have an unassailable fortress/prison.

    Its probably not beyond human engineering now to dig a trench 100metres deep and a mile wide between Russia and "The West", from Arctic to Mediteranian, or perhaps Indian.
    Expensive obviously.

  4. The classic function of fortresses for defence of the country was indeed to block lines of communications either by direct attecks (fortresses at rivers and canals) or by raiding behind an invading army.
    The invader's reaction was to lay siege with disproportionate forces (always risky because of food supply and illnesses).

    Fortifications also increased the necessary effort for looting and thus reduced the prospects of an invasion, possibly even discouraging it entirely.

    In relation to that trench or water canal which you mentioned: Indeed, during World War III such a vast obstacle along the German-German border (similarly mine-fields) could have done a brilliant job at squeezing the Warsaw Pact forces into a few narrow passages, as well as at delaying their whole assault long enough for the West to organize its airforces, armies and ship convoys from across the Atlantic.
    But even that hypothetical 100 metres wide trench will only protect you partially against land forces – and even that only temporarily –, but it won’t stop the enemy land forces for example from landing on your beaches, dropping parachutists behind the trench or sending commandos up your rivers, at night, etc. etc. . And for an infinite fraction of its construction costs even that trench is crossable too – after the enemy airforce secures its opposite margin, of course. So basically you need some sort of “100 metres wide trench against the enemy airforce” as well.
    Nowadays, a wall of S-500’s and Bofors Trinity’s should suffice to do the job simply at all altitudes, almost into Space.
    Come to think of it: Since absolutely no land invasion today is EVEN ATTEMPTED before definitive air superiority is achieved, all you need to protect your régime forever against an onslaught of whole World (!) is to invest profoundly in air defenses, nowhere else! It’s really as easy as that.

    Hey, where is my Nobel Prize?
