Is Gaddafi Teetering?

The CIA thinks so:

New U.S. intelligence assessments conclude that government forces, already beset with morale problems and a steady stream of defections, are now hard-pressed to find fuel for military vehicles after rebel troops shut down a key pipeline. If current trends continue, loyalists troops will run out of fuel by summer’s end, and the Gaddafi government will face a worsening cash and credit shortage because of international sanctions, the reports say.

While the momentum has generally favored the rebels for weeks, Western analysts are seeing troubles escalate on the loyalist side, possibly explaining the surge of interest in finding a negotiated end to the fighting, according to two senior U.S. officials who have seen the assessments.

Suppose his government collapses and he flees the country. Then what?
