The lesson most politicians learnt from Vietnam is that if you want to keep a war popular, keep the voters from seeing the real cost. The occasional funeral with bands and flags is fine. But proper support for PTSD, in serving troops and veterans, would not only cost a lot but focus attention on what's being done to "our heroes."
Ignore it, and the deaths and breakdowns can be safely buried among the general statistics.
