Tragedy in Iran

From the New York Times

The 51 freight train cars — hauling sulfur, fuel oil and other industrial chemicals — caught fire and blew up outside Neyshabur, 400 miles east of Tehran, IRNA reported. The villages that were badly damaged were made up of mud brick structures and sat within what officials said was a 12-mile diameter blast zone.

Yep, 12 mile blast zone. Why worry about the expense of nukes. Ground zero is seldom that big. Google says 200 dead. These people do not need this.
