I use this to have students analyze their opinions of the Vietnam War, and how they perceive the conflicts in Iraq, Afghanistan and other events. I use this in interactive notebooks, and often have the students color-code anything having to do with communism or socialism with a pink highlighter (pink... red) and then choose another color (I usually had them use blue) for capitalism, democracy, and for the U.S. I also use this with the PowerPoint "Vietnam War Escalation."
