When Worlds Collapse

Mark Ambinder nails the link between the weakness of the global economy and Obama's foreign policy options.  As far as economics are concerned the world really is flat and the prospects of contagion are freighting.    Money quote:

Where the discussion isn't going, at least in public,  (or the PR level), is the possibility that the first foreign policy crisis the administration will face will be the complete economic collapse of a large, unstable nation. To be sure, Pakistan is nearly broke, and U.S. policy makers seem to be aware of that; but a worldwide demand crisis could lead to social unrest in countries like Indonesia and Malaysia, Singapore, the Ukraine, Japan, Turkey or Egypt (which is facing an internal political crisis of epic proportions already). The U.S. won't have the resources to, say, engineer the rescue of the peso again, or intervene in Asia as in 1997.
