Weighing in on Obama's speech: Is Libya effort worth it?

(NECN) - Michael Corgan, professor of international relations at Boston University, says the president if walking a tightrope because a lot depends on what rebels do or not do:  whether they are able to oust dictator Moammar Gadhafi on their own, and whether the leader's own forces can be turned against him.
The president's speech noted that, starting Wednesday, that operations will be turned over to the North Atlantic Treaty Organization, which Corgan noted will be calling the strikes when needed and will determine which targets to hit and which forces to use.

If Gadhafi does not go quickly, however, that's bad news for the president, Corgan said. While Obama said the strategy does not include regime change, Ariz. Sen. John McCain, Obama's Repbulican opponent for the presidency in 2008, has questioned why not?

But Corgan says it's not so easy. Corgan said, nothing that very few outside Libya know exactly what is going on at the highest levels of government because it has been a closed society for so many years.

"Regime change is difficult. Who will emerge as the leader?" Corgan said.

Gadhafi has made it clear that no one who disagrees with him in any way is not going to have any role in his regime.
