Here I provide a complete analysis of Trident.
Military use
The British capitalist government has Trident missiles equipped with nuclear warheads that are launched from submarines. They are utterly useless in armed conflict as all they do is invite a huge attack.
Economics
The sole purpose of these missiles is to provide a mechanism for taxes to be diverted into the grasping hands of arms manufacturers, particularly the infamous Lockheed Martin. Claims by both the British government and the GMB trades’ union that retention (and upgrade) of Trident provides thousands of jobs are wholly vacuous arguments as the same workforce and costs could be used to build or operate something useful.
Conclusion
Militarily and economically, Trident is absolutely useless.

I think the questions to Cameron should be, under what circumstances would he use Trident and who is is aimed at?
Think the question should be under what circumstances would he kill millions of people and have millions of his own people killed in return?
It is far too easy for people to refer to the slaughter of millions as “Pressing the red button” without addressing the consequences of the action, it is similar to the “collateral damage” that covers up the slaughter of innocents in government actions abroad.
[…] Conversely, the UK Defence Journal’s reaction to reading my brief, but concise, dismissal of trident’s usefulness was pretence of a mock. (Link to blog: Trident – A full in-depth considered analysis) […]
