One Saturday night this summer, a foreigner fainted and fell to the floor of a Shanghai subway car.
The passengers around him scattered. Not a single person tried to help.
When the train arrived at the next station, hundreds rushed out, nearly trampling each other.
The incident was captured on closed-circuit cameras. Tens of millions in China have now seen the images, which have rekindled a long-running debate among Chinese about their national character as well as trust and fear in modern society.
It's hard to imagine a more compelling monument to the rise and fall of the Palestinian dream of statehood than the bombed-out ruins that the 1.8 million people of Gaza call their international airport.
About 2,000 years ago, the Roman Empire stretched from the Middle East all the way across Western Europe. A wall marked the empire's northernmost boundary, at one point less than a mile from today's border between England and Scotland.
The Roman emperor Hadrian built the 73-mile wall at this point to keep the unruly Scottish out. When the Scottish vote in an independence referendum on Sept. 18, they will be deciding whether they want to separate from the rest of Britain.
One byproduct of the recurring battles between Israel and its Arab neighbors is that Israel has developed a homegrown weapons industry that addresses its very specific needs.
Over the decades, this has included a number of cutting-edge technologies, from drones to night-vision equipment, which have been widely exported.
A more recent example is the Iron Dome, which was used throughout the latest conflict with Hamas in the Gaza Strip. The mobile missile defense system is capable of stopping short-range rockets from places like Gaza, the West Bank and southern Lebanon.
