There is a research center in the Twin Cities devoted to helping people who survived torture. Helping these people to shed those hellish memories would help them to work towards a better life today. Victims of "ethnic cleansing", a term that doesn't even begin to touch the horrors endured in Africa or Bosnia, could perhaps be given a better start.
PTSD has become a major problem in the services, with extended duty for some in combat zones.
The folks at strategy page keep saying that 100 days of combat or more results in about 90% of vets getting at least some PTSD. There has been a lot of talk of more post combat counseling and decompression time before going back to civilian life. I’m not sure if any of this has been done, but I’d be curious to know from vets here.
This conclusion about PTSD as a strict function of combat days is a big leap from the old days (5-10 years ago) that said that only some with certain genetic or psych predispostions were vulnerable.
