All quiet on the Western Front

The movies "All quiet...." main view is anti-war. It was made after world war 1, and was extremely popular. World war 1 was by many considered a very useless and costly war.  Many resources were lost, a lot of money spent, and thousands of soldiers died. In the end almost nothing was achieved either. It was a battle of countries showing off their newest technology for  killing another human. However, this movie became popular again during the Vietnam War. Just like World War 1, many soldiers, and citizens felt that the war was useless and costly. Millions of dollars were spent, and thousands of soldiers died in combat. The whole purpose of the war was to prevent communism from spreading....but instead the war resulted in all of Vietnam uniting under Communism. In other words all the money and lives lost served to purpose at all.
