Ulrich Krotz and Richard Maher, David M. McCourt and Andrew Glencross, Norrin M. Ripsman, Mark S. Sheetz and Jean-Yves Haine respond to Sebastian Rosato's spring 2011 article, "Europe’s Troubles: Power Politics and the State of the European Project."

"The divide, as usual, is between France and Germany over monetary policy. The French, along with their southern European allies in Greece, Italy, Spain, and Portugal, favor easy money, while the Germans, along with northern Europeans in the Netherlands, Austria, and Finland, insist on a tight money policy. Any hint of German capitulation to French demands of easier money will be the end of the euro. The first sign of wavering, the first inkling that a compromise is afoot, will signal to the markets that the floodgates for a river of euros are open, that fiscal and monetary discipline are history, that inflation will be rampant, and that the euro will be worthless."

Mark Sheetz of Columbia University comments on Michael Mastanduno's Spring 1997 article, "Preserving the Unipolar Moment," which asks whether realism is still a useful paradigm to explain U.S. grand strategy after the Cold War. Mastanduno replies.
