I thoroughly endorse what the Financial Times has to say. We need multilateralism now more than ever. We should not simply think ‘Europe First’, and:
The IMF needs considerable reform: its voting structure is out of date; its resources are too small; and its ability to lead the global debate on macroeconomic adjustment and exchange rates is too weak.
Here, here. Especially the point about leading the debate on macroeconomic adjustment and exchange rates. If you want to fight terrorism more effectively, perhaps here might be a good place to start.
