This would represent a significant change from Tunisia and Egypt, in which both leaders spoke largely to their own people, although they certainly made reference to "conspiracies" from the international community. Ghaddafi may be trying to draw the West in with the intent of offloading some of the frustration of protesters from himself. However, this is highly unlikely to be effective, as al-Jazeera has far more credibility in the Arab world than does Muamar Ghaddafi.
Nonetheless, the development is a case of "learning" by an authoritarian regime seeking to stay in power. Libyan protesters have learned from their brethren in Tunisia and Egypt, but regimes throughout the region are watching closely as well, adjusting their policies accordingly. Whether or not the learning will be effective, however, remains to be seen.
