Libya's problems would not look so dangerous if there was a proper government in place to deal with them. Instead, more than two months since Gaddafi was driven from his capital, there is still a power vacuum. No government has been formed because former rebels cannot agree on how to share out power. The new prime minister, appointed last week, is a professor of electrical engineering originally from Tripoli who spent most of the last three decades at universities in Alabama and North Carolina - and was chosen because he offends nobody.
