The movie is a snap of what happened, happens and would happen at war with lives, hopes, and disguise at stake. There is no wonder that the American soldier is depicted as one with a heart, with hope for life, and with a brain. Yet, if you look at the movie from an alien point of view you would understand that the soldier is a foreign land whom he has no idea why he is there, who he is fighting for, or even whether this war he's fighting and involved will change his world or the worlds of other. In other words, if your house is made of glass, don't throw at people stones. The producer tries to depict the lost souls who unwillingly fought for their countries or rather for their superiors and the so-called enemies who are on a mission to get back at them being pushed by what happened to them or to their countries. What separates truth, untruth, life and death is a mere wall that can collapse at any time.
