I'm assuming this count includes North Korea, Iran and Libya; he says that he knows of no other country in the Middle East to which he gave this information, so the locations of the other 17 or so targets are left as exercises for the rather alarmed reader.
Of course, given that A. Q. Khan (the head of Pak's nuclear program) was printing out four-color glossy brochures with his picture on them advertising nuclear capability, I suppose this shouldn't be too much of a surprise...
