Government's Fault

The reason why these characters are in these situations is because of the government involving itself in the war. They don't want to keep sending people because they waste money doing so, so instead they try to keep the ones they already have deployed in the war zones. That is why they keep raising the amount of missions necessary to be performed in order for a soldier to leave. And also, what I thought to be very interesting, is when the narrator tells us that one mission, Yossarian flew over the target twice before he bombed it instead of once, such mistake lead to the death of a fellow soldier. Instead of Yossarian being dismissed, or even punished for such mistake, he is awarded a medal. The government wanted him to stay around so they ignored his mistake.
