Of course you are right, Larry, it was South Korea - 126 dead, compared to 12 in the sarin attack, though the sarin caused a lot more injuries. Seems it was paint thinner rather than gasoline, but still.

I'm actually surprised that there haven't been a lot more attacks like this in the US - very glad, but still surprised, given that it would be relatively easy plus the reported levels of anti-US feelings among various radicals.

Think of the fear that the DC snipers caused, and they were just two idiots with a rifle, not dedicated terrorists.

As you said, a broad spectrum of effort is needed to conter such threats, I hope intelligent plans are underway for just that.
