it seems as if the man in the poster (Uncle Sam) is talking directly to you saying that he wants you to come and help fight for your country. This poster has been said to been used for World War 1 and World War 2  Flagg (the creator of the poster) was said to used a modified version of his own face for Uncle Sam. Then came another quote from John. F. Kennedy "Ask not What Your Country Can Do for You, Ask what You can do for Your country". This is another motive for making people want to join the U.S ARMY it makes you think "Man! I'm not really doing anything to help my country.... maybe I should join the ARMY!  then I'll actually be worth something to my country!"
