LONDON — Yemen has suddenly joined Afghanistan and Pakistan as a risk to global security. Indeed, it is increasingly seen as a nascent failed state and potential replacement host for al-Qaida.

The attempted bombing of a Detroit-bound airliner on Christmas Day by a young Nigerian man trained by al-Qaida in Yemen appeared to open the West's eyes to the country's problems. Following that failed attack, U.S. President Barack Obama and British Prime Minister Gordon Brown jointly pushed a conference in London to propose solutions for the previously overlooked crises in Yemen.

But if the conference focuses too narrowly on al-Qaida's presence in Yemen, it will do more harm than good. Instead, the conference must aim to address broader issues of political and social stability within the country.
