The killings of some 16 civilians in Afghanistan on Sunday allegedly by a U.S. soldier are raising new questions about U.S. military strategy: whether the surge of American troops worked, and whether the U.S. troops have won over the Afghan people or alienated them.
The place where the killings happened was a "no-go zone" for American and even Afghan troops as recently as two years ago — it was Taliban country.
In Afghanistan, the killings are called "green on blue" — that's when an Afghan soldier or police officer turns his gun on a NATO ally.
There was a wave of such violence just last month after U.S. soldiers accidentally burned Korans. Over the next week, six Americans were killed, apparently at the hands of Afghans working with the U.S.
The top U.S. and NATO commanders in Afghanistan think they have some answers to this recurring problem, and it's up to U.S. soldiers like Capt. Joe Fritze to see if they work.
Every May, Russia displays its military might in a parade on Victory Day, commemorating the surrender of the Nazis to the Soviet Union in World War II.
The marching men and rolling tanks put on an impressive show, but Russia's military, and especially its defense industry, has fallen on hard times.
"The industry, much like other parts of the economy, hasn't seen proper investment for over a decade, if not more," says Lilit Gevorgyan, a Russia analyst for the defense industry consultant IHS Jane's.
