The question, then… is, when and if things turn out well in Iraq, will journalists even be able to recognize it?
Why do people say "if and when"? (Or, in Kaplan's case, "when and if".) "If..." and "when..." are two entirely different logical/grammatical constructs, and the whole point of saying "if" is that there might not be a "when." Clearly both won't always pertain, so it should be "if or
