From The Times:

The growing influence of Islamists in Libya raises hard questions about the ultimate character of the government and society that will rise in place of Col. Muammar el-Qaddafi's autocracy. The United States and Libya's new leaders say the Islamists, a well-organized group in a mostly moderate country, are sending signals that they are dedicated to democratic pluralism. They say there is no reason to doubt the Islamists' sincerity.

Okey-dokey, then. That's good enough for me.
