If you had attached some options to choose, it would have been much easier for me to give you the right answer in the way that you need. Fortunately, I have two answers but I am not sure that you have the same in your task so I will just share them and all you need is to choose the best suitable. So, the options are : 1) an anger and rage at the government and 2) a general disillusionment with war. Hope that one of them will help you.
