How can the international military coalition opposed to Muammar Gaddafi, the Libyan leader, bring peace to that country without getting caught in a prolonged military conflict?

The US, France and Britain successfully enforced a UN Security Council-approved no-fly zone over Libya to stop Gaddafi's forces from attacking rebels in the east.

But many are wondering if those airstrikes will be enough to deter a defiant Gaddafi and whether international troops are needed to push back Libyan government forces.

Complicating matters is a growing chorus of criticism from a number of nations including Turkey, China and India. Also, Vladimir Putin, Russia's prime minister, has called the UN resolution a "medieval call to crusade".

We will be discussing those issues with US congressman Dennis Kucinich who has been critical of Barack Obama's decision to strike Libya; Ali Suleiman Aujali, the former Libyan ambassador to the US, who now represents the Libyan National Transitional Council in Washington, DC; and military strategist Sam Gardiner, a retired American Air Force colonel.
