Katie Couric's Notebook: Afghanistan

At least 34 Americans have been killed, and suicide bombers have launched an onslaught on government buildings. Those haunting images of Bowe Bergdahl, the soldier held captive by the Taliban, are another startling reminder that this war is far from over.

As the Taliban gains strength in remote regions, Hamid Karzai is losing his in Kabul. Corruption and chaos have undermined his rule and weakened support for American involvement.

This single country represents a world of challenges for the United States. The road forward will be strewn with massive potholes, barricades and IEDs, as Americans try to keep terrorists at bay by building a better nation.

It's a terribly dicey and complicated situation, but we can only hope, for the sake of the Afghan people and the safety of the world, one day, the tag line: "Graveyard of Empires" will be buried for good.

That's a page from my notebook.
