Okay, nowI have a suspicion again... But whatever:
First of all, quotes (in general, but also in this particular case) do not prove your point, that's just namedropping.
And assuming anyone here would buy the book you linked to be allowed to question your statements is bold at least.
Comment: It is not
'namedropping' it is fact + history + reality and therefore RELEVANT.
Now for the content:
OP posed the question whether food should and can be a strategic resource in HoI4, just like steel, oil etc. Concers regarding undesirable (and undesired) implications to that force the limitation on military aspects, narrowing down the
strategic importance alot!
Your approach on this issue was to introduce figures about how many food was used in operation Barbarossa by horses, at which point I thought of a joke. Because, and I am repeating myself here, this is hardly a strategic significance when compared to e.g. Germany lacking tungsten for artillery or rubber for planes. You can get food for horses if you need to, also very well within your own country. Getting it to the troops is another issue (not a strategic one!) and btw the right interpretation of your "Sun Tzu"-quote.
Comment: If the USSR has initiated a SCORCHED EARTH STRATEGY - and YOU are the General Office Commanding [GOC] then you will never
'get food for horses if you need to' - as per your posted comment. The historical records are clear - there were
750,000 horses in YOUR armies. If you do not feed and water them, who or what will put your artillery units into position?
But I have the notion you do not want to talk about food or strategic resources but logistics. Thing is, this is not the thread for this. It is not only not about food logistic, it is not at all about logistic. Even strategic ressources do not use a detailed logistic system, just the good olde convoi at max.
Comment: Consider - irrespective of whether it is Guns or Butter that you manufacture, these products are of NO value if you cannot deliver them to the FRONT-LINES where they are needed. The connection between manufacturing + supply always requires LOGISTICS for successful OPS.
Recall
: Generals win battles - Logisticians win wars
While I am writing this,
@vector1 makes the point that food may be seen as included in general supplies, which I fully support in terms of game model. However, this has nothing to do with food being a strategic resource.
That sounds like you want me to search for a quote that proves you are not on topic. And while I have my problems with your claim regarding academic method, I'll just let you have it since this is no academic discussion.
Comment: Every endeavour in human research and development
requires a sound basis in science and academic effort.
Example: Do you suppose that antibiotics just
'fell out of the pharmacy without any research and academic work?'
But to end with a more friendly approach: Could you rephrase your thesis regarding food as strategic resource? Maybe it is all a big misunderstanding.
