I cannot imagine a context that would some day, in some manner, make the monstrous crime of September 11 an understandable or comprehensible political act
After September 11, the European governments have completely failed. They are incapable of seeing beyond their own national scope of interests.
Perhaps at a later point important developments will be traced back to September 11. But for now we do not know which of the many scenarios will actually hold in the future.
