Or we simply fixed them, much a you'd fix a cat or dog. See http://projects.wsj.com/lobotomyfiles/
"The U.S. government lobotomized roughly 2,000 mentally ill veterans—and likely hundreds more—during and after World War II, according to a cache of forgotten memos, letters and government reports unearthed by The Wall Street Journal. Besieged by psychologically damaged troops returning from the battlefields of North Africa, Europe and the Pacific, the Veterans Administration performed the brain-altering operation on former servicemen it diagnosed as depressives, psychotics and schizophrenics, and occasionally on people identified as homosexuals.

"The VA documents subvert an article of faith of postwar American mythology: That returning soldiers put down their guns, shed their uniforms and stoically forged ahead into the optimistic 1950s. Mr. Tritz and the mentally ill veterans who shared his fate lived a struggle all but unknown except to the families who still bear lobotomy’s scars.
...
"During eight years as a patient in the VA hospital in Tomah, Wis., Mr. Tritz underwent 28 rounds of electroshock therapy, a common treatment that sometimes caused convulsions so jarring they broke patients’ bones. Medical records show that Mr. Tritz received another routine VA treatment: insulin-induced temporary comas, which were thought to relieve symptoms.
‘Anxious to Start’
The VA hospital in Tuskegee, Ala., asks permission to perform lobotomies.
"To stimulate patients’ nerves, hospital staff also commonly sprayed veterans with powerful jets of alternating hot and cold water, the archives show. Mr. Tritz received 66 treatments of high-pressure water sprays called the Scotch Douche and Needle Shower, his medical records say.
"When all else failed, there was lobotomy."
(My emphasis)
I do like the phrasing, and restore America. The one answer, in retrospect, is that "No one expects the Spanish Inquisition." The other answer - some of those soldiers & civilians never really came back from the war. They were lost somewhere over there, & only their bodies came home again.
But as their horrors didn't fit the narrative of the booming 1950s, they were neatly excised, their stories left on the cutting room floor, as it were. Just as the Dick & Jane primers never show so much a bald spot in that endless perfect suburban lawn, we shoved these men & women - & their stories, & their suffering, & their families & loved ones - under the rug.
