…I work occasionally at the VA as a psychiatrist in both inpatient and outpatient settings. My impression is that the men going into the recent wars are far less psychologically healthy then the men who went to WWI, WWII, or Korea. The prior longitudinal studies of the wars of the first half of the 20th century, such as they are, do indeed suggest that most men exit war with similar psychological profiles as to when they entered. Could the recently documented ‘sense of loss’ so many returning veterans express reflect something similar to inner city youths and gangs, namely, that the camaraderie of combat and order of military life provided the paternal presence they lacked growing up? Military life and combat provided what communities and families had provided similar men when they returned from WWI and WWII. Take away the military life and combat, and they are left where they were prior to joining.
That is from a recent post on reading.
