Regardless, I don't think we'll be seeing anything like a recession this time around - the Fed has learned from their screwup in 2008 and won't make the same mistakes again.
Edit: A slowdown in growth as a result of e.g. problems in Europe or China might happen, but this would not be a "recession" as commonly understood. It would look very different in the data (inflation, unemployment rates and the like) and the appropriate policy response would be completely different as well.
Edit 2: And the Fed did a lot more than just "lowering interest rates" in a direct, trivial sense (and they _had_ to, since interest rates _were_ indeed quite low even before the Great Recession was widely acknowledged as such. I'm not sure why people - including Krugman - are now suggesting otherwise). I don't think many people would disagree that these policy measures were highly effective, but Krugman used to be a very vocal skeptic.
