The Pentagon says the war in Afghanistan is showing significant progress.
FOX News Radio's Steve Taylor has more from Washington in our ongoing series on national security:
Panetta: "I thought it was important to remind the American people that there is a war going on in Afghanistan."
Afghanistan remains a tough fight, says Defense Secretary Leon Panetta, but Afghan troops are taking over more and more.
Panetta: "Two-thirds of all of those in uniform defending Afghanistan are now Afghans."
The Secretary blames the recent ambush killings of Americans on a frustrated enemy.
Panetta: "The Taliban has not been able to regain any territory lost and so they're resorting to these kinds of attacks to create havoc."
Panetta says the attacks have not disrupted operations.
