The coup of 1973 and the attacks of 2001 were very different in character. But the contrast in the responses of Chile and America to their respective national traumas is instructive, says Patricio Navia.
The al-Qaida strategy of attacking the United States created its own form of blowback. But the triumph of militarisation after 9/11 exacted a deeper cost on the world, says Vicken Cheterian.

We are systematically discouraging the development of a humanitarian regime at sea, accepting death rather than uncontrolled immigration. Saving 'boat people' comes at a cost few are willing to take, says Nina Perkowski
A flawed response to terrorism on its soil brought the United States low. The lessons are also for the rest of the world to learn, says Rein Müllerson.
