How would today's American teens deal with the conflicts of war?
Thisis simple, just check the local newspapers for any service members returning from Iraq or Afghanistan. This will give you a glimpse into how our youth are handling the stress of combat and the particular issues related to the post combat.
I think they deal with it rather well, so well in fact that almost all military conflicts in last 30 years can be blamed on them. Their economy currently cannot survive without the input of war.
