John McCain told supporters Sunday that Iraq is a "tough war" that isn't "going to be over right away," then warned: "There's going to be other wars ... I'm sorry to tell you, there's going to be other wars. We will never surrender but there will be other wars."
As the Huffington Post's Sam Stein notes, McCain "did not elaborate who the United States would be fighting."
