Robert Wright makes a good point here, one that others have made before him and that we continue to ignore at our peril. We pay a huge cost for being (we think) the "sole superpower" and de facto global cop. We pay for it financially and in our standing in the world. We do need more collective efforts, which we used in the Cold War (think NATO). We were always the biggest contributor, but never the only one. Maybe, to some extent, we've always been suckers. However, it's time to stop. We have to get beyond the paranoia of shared sovereignty. We need to work our real collective action strategies.
Well, one can hope.
