North Korea's advancing nuclear weapons program isn't the only news to unnerve arms-control experts this summer. A new survey has revealed that Americans are surprisingly willing to make a first nuclear strike — and kill millions of civilians abroad.

But many Americans say it's quite thinkable. The taboo may be eroding, or it may never have been the protective barrier people thought it was.
