Greetings from Afghanistan. I arrived here now almost a week ago and there is so much to share about this experience that it's hard to know where to start. I was immediately struck by the contrast between the incredible beauty of the landscape here and what humans have managed to...

On the eve of the G-20 summit last week, President Barack Obama gave a long interview to the Pittsburgh Post-Gazette, in which he said that even during his days as a community organizer in Chicago he was never a big fan of mass protests.

With the clear intention...

It would be nice to celebrate the recent withdrawal of the remaining British troops from Iraq as the end of the UK's direct involvement in the military occupation there. But such festivities would unfortunately be premature.

The killing last Sunday in Baghdad's Green Zone of two armed contractors...

With little public scrutiny, robotics is quickly revolutionizing not only how war is fought, but who fights in war. While the U.S. military first began to experiment with remote-controlled weapons during World War I, the Pentagon had no robots on the ground when it invaded Iraq in 2003, and only...

With the release of its annual report on China's military capabilities at the end of March, the Pentagon is doing its part to keep alive the threat of the red menace.

After raking in more than a billion dollars from its contracts in Iraq, Blackwater is finally being forced to leave the country that it has terrorised for so long.

"If you don't vote, then you can't complain." So goes a refrain that is reflexively regurgitated to anyone who questions the efficacy of voting. Generally it's accompanied by a smug look, indicating that in their eyes you're hopelessly out of touch with reality. But after cutting through the hype, are...

Health care has become the top domestic issue for most Americans this electoral season -- and for good reason. By nearly any measure, the system simply does not work. Heart-wrenching stories of its shortcomings can be read ad infinitum. And while they rightly evoke feelings of empathy and anger, experiencing...

While recent polls reveal that 60 to 70 percent of Americans have soured on the war in Iraq, most of these people should not be mistakenly labeled "antiwar."

Many of those calling for the troops to come home could more properly be called "anti-this-war." "We...

In the United States, where the vast majority of the population (82 percent according to a recent Newsweek poll) identify themselves as Christians, one of the most important steps we can all take to ending not only the war in Iraq, but all war, is to remind people of faith...

With the U.S. consuming a quarter of the world's petroleum, President Bush courageously admitted the obvious during his 2006 State of the Union address: "America is addicted to oil."
