Security is rather in depth - it's akin to N dimensional chess - and developing the structures on that around identification, detection, protection and recovery make it a massive undertaking. I would say you have many types of people in it - the roles vary in requirements - from emotionally intelligent, to in depth logical, to being able to function under extreme pressure effectively. So I find your analysis a little obtuse.
My wife does accounting/tax - apart from the pass the exam or be fired each year, it's a very stable way of life. Personally I see the work as being boring/volume pressure but they make up for it by any chance to party/socialise as it's seen as a necessity due to the flatness of the role. So I can appreciate your point in the accountancy career.
So the question is - what next?
Putin is busy attempting to rebuild his military, so is the European and US. His shock and awe attempt to recreate the panzer blitzkrieg tactic failed, and now faces a long term plan where Russia attempts to drain the population within the generations of Ukraine to support a repeat offensive in the next 5 years (thinking of the age of Putin - he will want to cement his claim to fame along side Leonid Brezhnev's tomb).
However Russia's tactic of throwing people removes the industrial and research heart.
China will only support for so long, it's providing stockpiled arms but has the ability to ramp up production of previous generation equipment that is not of use commercially but can be used in producing previous generation weapons (ie in the last 15-5 years) that still can do the job. Russia's trade of raw materials for this continues to drive for now but it needs outside trade to drive its faltering economy. That trade requirement is the Russian's Achilles heel in this.
