Another War in the Middle East?

Following riots and opposition from Qaddafi's troops,a no-fly zone was imposed on Libya. Now, after anti aircraft artillery has been destroyed, allied planes have been bombing Libyan ground troops more intensely. These planes are attacking mainly in urban cities which means there is a high chance of civilian casualties. The attacks lead the public to wonder where the line is between all out war the more limited mission of enforcing a no-fly zone. In a N.Y. Times article, other difficult questions are raised:

As the war intensified, Mr. Obama faced new pressures in Congress. The House speaker, John A. Boehner, sent the White House a letter on Wednesday, demanding answers about the cost of the war, an exit strategy and when the United States would hand off the lead role to the allies. He also asked a question central in Washington: “Is it an acceptable outcome for Qaddafi to remain in power after the military effort concludes in Libya?”

While most of the public seems to be against the war, everybody is wondering this same question. What will happen if Qaddafi leaves power after his long and vice-like reign? The U.S. already has many enemies in the middle-east and placing a dictator more favorable to the U.S. in power could have many negative effects. Can we afford to be in another war right now? Obama faces many tough choices and the future of much of the world depends on his decisions.
