My own take for why this is a problem has to do less with the abilities of any particular SecDef or fears about the increasing politicization of the military and more to do with long-term norms about control and direction. 1/14 https://twitter.com/mattyglesias/status/1336308529695760391 …

There is a trap and it is relatively easy to slide into where the normative assumption (among the public and elites) is that civilian leaders ought not interfere with military leaders due to the latter's superior expertise. 2/14

That risk is particularly acute in a society which generally assigns high moral qualities to service personnel and low moral qualities to politicians (as we do). There is already a lot of 'if only the politicians would let the generals do the job' popular discourse. 3/14

The thing is, states where the military has effectively insulated itself from civilian control have pretty consistent records of awful decision-making. The classic examples of this are Germany, 1871-1919 and Japan 1920-1945. 4/14

The thing is, civilian leaders have a very different job then military ones. As Clausewitz notes (drink!) the political leaders manage the 'when/why' of war (the political object) whereas the military leaders manage the 'how' of war (dealing with friction, etc.). 5/14

Clausewitz is quite clear that there is subordination between these elements and that the political object is supreme - that's the significance of 'war is policy by other means.' 6/14

But the creation of a norm whereby the only people fit to make military decisions are military people fosters an independence of military leaders from civilian direction and thus tends to prioritize the 'how' over the 'why/when' to disastrous effect. 7/14

That's how you get military leaders backing Germany into a war with France because in 1914 because their plan didn't allow for anything else - they let the 'how' of winning the war dictate the 'why' - 'why fight France' - because that was the how-plan! 8/14
