Catch-22: How does it relate to my definition of American Literature?

In the American Literature definition, I talk about how it reflects the emotions, themes, and events of the era from which it was created. Then, war is looked at as an example. Taking a look at war helps to show the emotion expressed through literature about the war. Each time period will also be looked at for the project along with each major war during that time. Many emotions have been expressed through literature about war, especially anti-war feelings. Writers wrote about how war was irrelevant to the time and discussed how it was a silly way to solve problems. In the project, Catch-22 will be an example used because Joseph Heller, the author, expresses the absurdity of war through the cooky characters and stupid idea of the catch-22.
Catch-22 is about a bomber, Yossarian, who doesn't want to be in World War II. His view on his friends make them seem idiotic and crazy. All of his views on the different situations he is put through is horrible and fatal. One rule which he dislikes the most is the catch, catch-22. This explains how soldiers are allowed to go home and leave the war if they are crazy, but in order to be identified as crazy, they have to express that they are crazy. The problem with that is, if they tell they're crazy, they aren't because they are sane enough to know they're crazy. To Yossarian, however, everyone is crazy for wanting to fight in the war. Showing that Yossarian thinks everything is crazy shows how he dislikes the war. This reflects how Heller didn't like the war which he thought was crazy, altogether. The dislike for the war shows that some people didn't want to be involved in a war. This shows that wars should not be the answer to situations and problems but should, instead, not happen at all.
