What does Joe realize at the end of the book? Who is he pointing the gun at?

joe realizes that he is the future. what has happened to his body, to his soul, is the future. it is what the masters of war want - the authority in society. the authority that is leading our country to more and more fighting. the authoritative people who keep these wars going on, one after the other. because joe knows that WWI, this war is not the end. it is only an example. and he knows that the hospital will not go with what he desires - to show people the threats of war, the devastation and the terror- they wont do it because of the very reason that joe wants to show people. the hospital wont show people Joe, they wont show them his warning of the future. because they need people in those wars. the masters of wars need people to fight. and joe knows the future - he has seen the airplanes, he has seen the wars, hes seen romance and dreams turn to horror and darkness, to screaming boys and crippled fathers, hes seen starving mothers, headless babies, dead mass silence from the amount of innocent deaths. and the masters of war, the people that enforce those regulations, keep joe a secret because they need these realities to be secret. because if they werent, people wouldnt fight. they need people to fight. and he realizes that it really is the little people vs the big people. the soldiers, the civilians, the people of the world against those who enforce evil, who promote it. who continue these awful devastations for their own gain. but joe goes into taking the voice of the people as one - for he goes against these masters of war - he declares their injustice, their root of the problem - how they are the ones who force those who wants only to live to kill others who only want to live. and how they use the people, use the men of peace, throw their slogans at them, their lies. and joe says yes, do that all you want. and we will follow you and do waht you say - but the guns will be pointed at you. the guns will be pointed at the masters of war. the people against the authority. authority/war vs. peace, people. that is the future. that mess is the future.

i hope i understood this right. lol
