A symbolic, not a real victory

On May Day, US President Barack Obama took the world by surprise when he announced that Osama bin Laden had been killed.

Without doubt, the death of the Al-Qaida leader is a great achievement in the global fight against terrorism. The spontaneous celebrations that broke out across the US show how eagerly the Americans were waiting to see this day.

History's most expansive, expensive and exasperating manhunt has finally ended, but the most expensive war against terrorism still has a long way to go.
