Shock and awe of 9/11 are still with us as US on brink again
Tomorrow is the 12th anniversary of 9/11, the events that changed America forever and began a new narrative in world affairs which is still playing out.

The 'Arab Spring', ostensibly a popular revolution against despotic regimes has been a mixed blessing with uncertain outcomes. Egypt is in turmoil. Syrian leader Bashar al-Assad's alleged use of chemical weapons on August 21 against civilians and armed opposition forces, and the potential response of western powers, is just the latest episode in a long-running saga flowing from that terrible day.
