If your next door neighbour were to aim a cannon from the bottom of their front garden squarely at the front of your house what would you do?
Obviously this is a loaded question (ha ha).
You could try to sabotage the cannon because you’re never going to be able to armour your house enough to withstand the shot. You’re never going to be able to shoot the cannon ball out of the sky with a surface to air missile, you simply won’t have time and won’t have enough speed and momentum to change the outcome.
What you do is buy a cannon and aim it at the front of your neighbour’s house.
Mutually Assured Destruction (MAD).
When your neighbour comes home and sees your cannon aimed at his home he might decide to buy a second cannon and point it at your house. The neat thing is you don’t have to keep up with the Joneses. One cannon is all it takes to level his house no matter how many he points at you.
All he gets from multiple cannons is redundancy, the ability to maintain one (and remove your sabotage attempts), and the ability to use one for training. All the time another still points at your house.
We’ve mentioned sabotage a number of times which demonstrates why it would be better if the weapon were difficult to detect, track and target. Submarine anyone?
Threat Mitigation
So, of the threats listed in a previous post the following highlighted ones are now deterred:
Tier 1
- Terrorism
- Cyber Attack
- Natural Disaster
- Overseas Military Crisis (drawing in the UK)
Tier 2
- Chemical, Biological, Radiological or Nuclear Attack
- Overseas Instability (leading to points 1, 2 and 4 above)
- Organised Crime
- Communication Disruption
Tier 3
- Conventional Attack
- Smuggling (weapons, criminals, immigrants, narcotics)
- Energy Disruption
- Nuclear Accident
- Resource Supply Disruption
So none of the tier 1 threats but certainly the high impact ones!
The thing about Trident is that it is very, very expensive but unfortunately the only real credible deterrent against large-scale attack against the UK. Without it we would be sitting ducks prone to nuclear blackmail and extortion.
Nuclear Terrorism
What about non-state actors obtaining a nuclear warhead and detonating it in London?
As can be seen by recent news footage of the Iranian nuclear programme it is very difficult and expensive to produce weapons grade materials. In addition it should be relatively simple to appreciate that the relative purity of these materials is difficult to control exactly. Uranium is purified using centrifuges. These are mechanical devices and cannot remove 100% of other heavy elements. Therefore when the bomb detonates, the fallout that remains gives us a distinct signature that will correspond with a single production batch.
This means we know who manufactured the warhead. We can hold this nation responsible and retaliate accordingly. It is part of the deterrent for even getting into the nuclear business in the first place. One of the responsibilities of playing God.
If you play with fire you must be prepared to be burned.
