ASHKELON, Israel — The roar of sirens echoed across this sun-kissed city Monday afternoon, and in a heartbeat the woman in the pink bikini was out of the pool, shepherding her three young kids to the nearest shelter.

And then, a boom: The rocket had been shot down.
The kids jumped back in the seaside pool, and their mother returned to her tanning. Through it all, the lifeguard had barely stirred.
