Self-quoted from a G+ discussion in which the following Rumsfeldian aphorism came up:
You go to war with the army you have, not the army you might want.
It is a truth I think greatly underappreciated (especially by politicians, alas) that unless you have paid the ridiculous-even-by-the-standards-of-US-defense-budgets amount of money necessary to have a genuinely omnicompetent army, then it would behove you to go to war in a manner befitting the capabilities of the army (or space navy) you have. Otherwise bad things will ensue… as we have seen a lot in reality, including thanks to Mr. Rumsfeld drawing exactly the wrong conclusion from his above-quoted aphorism.
(In the Eldraeverse, for example, the Imperial Military Service is a finely optimized instrument for patrolling, raiding in force, special operations, and glassing things from orbit. It is, consequentially, pretty much pessimal for tasks like “occupation”, and/or “nation-building”, and if the Minister President asks for that sort of thing, it’s the job of the First Lord of the Admiralty to look him in the eye and say “no can do, sir, unless you give us the budget and the time to develop doctrine and new units for the job”.
…this does occasionally result in more glassing of things from orbit than might be ideally required, but, y’know, it’s a resource-constrained universe and it’s not like they weren’t quite clear up front as to what the steps of this dance were, belike.
Although it is occasionally convenient that the chaps over at State & Outlands can point at the IMS and say, “Well, obviously we’re not out to conquer anybody; just look at our force mix. We couldn’t if we wanted to1.”
1. Spoiler alert: they could, but it would be expensive, inconvenient, and inelegant, thus unthinkable unless really provoked. Glossing over this sort of subtlety is what they pay the diplomats for.
