On the day after Osama bin Laden’s assassination, we came across a throwaway line among the stories on the 9/11 mastermind’s death: The U.S. commando team that took down the al Qaeda head was made up of 79 soldiers -- and one dog.

Good thing, then, that we already had Chief Canine Correspondent Rebecca Frankel on staff -- who was a grizzled veteran of the war dog beat for Tom Ricks’s Best Defense blog. Frankel knew intimately the value of dogs in the military -- a long legacy harkening back to World War II. and with thousands of their counterparts today serving with valor from Baghdad to Kabul.

Thus was born the War Dog photo essay, which, along with its successor, became FP’s most successful feature ever, with a whopping 11 million page views. Frankel continues to write a weekly column for Tom Ricks’s Best Defense blog, where she profiles canines and their trainers on deployments across the world’s war zones.

Anders Behring Breivik, a far-right xenophobe, shocked the world when he murdered 77 people, many of them children, with a car bomb attack in the Norwegian capital of Oslo and a shooting rampage on a nearby island on July 22. These images of Norway’s cushy penal system -- where prisoners have flat-screen televisions and mini-fridges in their rooms -- stood in stark contrast to the cold-blooded horror of Breivik’s crimes.

When the U.S. war in Afghanistan began, the first iPhone was not yet a gleam in Steve Jobs’s eye -- and forget having an app for that.

The Bangkok-based Dhammakaya movement may have begun as a reaction against the excesses of Buddhism in Thailand, but it soon developed cult-like rituals all of its own.
