Nikolas Gvosdev and Ray Takeyh argue that the justifying of America's Libya campaign solely on humanitarian grounds marked a fundamental break with past U.S. policy prescriptions for such military interventions.

Richard N. Haass says many of the world's bad guys departed the scene this past year, but looking back, 2011 was a year of great transition—not of transformation.

Isobel Coleman argues that in Libya, Egypt, and elsewhere, overthrowing male dominance could be harder than overthrowing a dictator.

John B. Bellinger III argues that Libyans should be allowed to choose whether they want to try members of the Qaddafi regime in their own courts.

Senator Carl M. Levin (D-MI), chairman of the Armed Services Committee, discusses U.S. involvement in Libya following Qaddafi's death, as well as progress in Afghanistan and possible federal budget sequestration with CFR's James M. Lindsay.

Mohamad Bazzi says that unfortunately for him and for Libya, Muammar al-Qaddafi betrayed his own revolution, just as the other Arab strongmen of his generation had. His death marks the end of the rule of these old-style nationalist leaders.

Isobel Coleman argues that a stable, prosperous Libya undergoing a process of democratization will enhance the chance of successful transitions in neighboring countries such as Tunisia and Egypt.

While Qaddafi's death is a victory for Libya's interim government and its international backers, analysts caution that the country's new leaders will have to resolve factional disputes and establish a functioning civil society ahead of democratic elections.

Ed Husain argues that while the death of Muammar al-Qaddafi lifts the morale of the besieged protestors in countries like Syria and Yemen, it also offers clues to the real risks of chaos and extremism that can spread in the region.

Post-Qaddafi Libya will face difficulties with rebel infighting, the anger of Qaddafi loyalists, and more, but the long-time dictator's death also creates an opening for a more peaceful country. CFR's Richard Haass, Ed Husain, and Ray Takeyh weigh Libya's prospects.

Robert Danin, CFR's senior fellow for Middle East and Africa studies, argues that the international community needs to remain involved in Libya after Qaddafi's death.

Disunity among Libya's rebels, a growing Islamist radical movement, and angry Qaddafi loyalists will mean a continued need for NATO involvement to check a possible slide into chaos.

In four decades of rule, Qaddafi chased doomed adventures that isolated his regime from Arabs and the world. Libyans now have a chance to recast their state and reintegrate with their region, says CFR's Ray Takeyh.

The reported death of Muammar al-Qaddafi marks a dramatic end to his sway over Libya. Libyans now need considerable Western help in securing and rebuilding the country he leaves behind, writes CFR President Richard N. Haass.

Micah Zenko argues that the ouster of Muammar al-Qaddafi will motivate other dictators to seek out nuclear weapons.

Despite the fall of the Qaddafi regime in Libya, humanitarian intervention still has plenty of critics.

Micah Zenko argues that overreaching Western eagerness to help Libya's rebels will now make it more difficult to line up meaningful outside support for Syria's opposition.

As Libya moves ahead with a leadership transition, it faces challenges including restarting the economy, dealing with humanitarian abuses, and the rising influence of Islamists.

Max Boot says that while Qaddafi has fallen in Libya, it is too soon to tell whether Operation Unified Protector is a success.

The Syrian regime's brutal crackdown on peaceful protesters didn't trip the same alarm bells as Libya's did for the UN Security Council, but the international community is gradually losing patience with Assad, says expert Edward Luck, a special advisor to the UN secretary-general.
