Philosophy and Public Affairs: Thomas Nagel's "The Problem of Global Justice"
Read this article. Nagel does not espouse the virtues of patriotism and what global theories of justice miss in their construction. Instead, Nagel questions whether it makes sense to speak of justice in a global context--at least at this point in time--whatsoever. In short, although variants of global justice might seem attractive, they are nonsensical and take us away from the meaningful work both theoretical and applied left to be done with regard to domestic justice.
