the planned diplomatic service will not contain enough experienced military personnel.

Maybee im missing some detail thats obvious to Serious people, but, erm, dont we want say, people with skills in things like talking to people, working as diplomats, rather than people whise primary skills lie in shooting, stabbing and blowing up their neighbouring human beings? Surely one ot the biggest arguments in Diplomacy is "If we dont sort this out like reasonable people, then we have to resort to the knuckle dragging lumpswho we keep in the cupboard at the back for when things get stupid, and they break the crockery and mess up the garden, so best if we can talk it out first" So you keep the miliatry away from the negotiating tables  unless its really necessary.

Any idiot can face a crisis - it's day to day living that wears you out.
