In the first instance, therefore, global terrorism created a kind of global community sharing a common fate, something we had previously considered impossible.

And it also became clear that these conditions of inequality and historical injustice have given rise to a feeling of hate in the world - a deeply felt hate that cannot easily be overcome with a few good words.
