The deadly terrorist attack on Kabul airport is a grim reminder that Afghanistan will remain a global problem long after America leaves, and that the Taliban isn’t totally in charge on the ground. President Joe Biden vowed to strike against the extremist group while sticking by his plan to continue the U.S. evacuation through Aug. 31.

The Family Feud Behind a Weight-Loss Camp

For five decades, the children at Camp Shane shed pounds, made friends and found romance in the Catskill Mountains of New York. The camp inspired the 1995 Disney film Heavyweights and was featured in BBC and MTV documentaries. But behind the scenes, a fierce succession drama was playing out.
