From the NYRB‘s first attempt to make sense of the 1987 Palestinian uprising:
As the situation hardens, rocks and stones will not necessarily be replaced only by revolvers. During the last few weeks I have several times heard officials in the US and Israel talk about sophisticated devices of terror, including atom bombs miniaturised into suitcases, being introduced before long.

Update (16 July, 2015)
Hertzberg had been worrying about this for a while:
There are increasing rumours that the United States possesses the technology to package an atom bomb in a suitcase. What an advanced superpower knows now, hole-in-the-wall terrorists will know in five years. The nightmares of James Bond movies and spy novels—of cities and nations being held to ransom by will-hidden small nuclear packages—is not far from reality. Is it too farfetched to imagine that such terrorists will show up in the Middle East sooner than anywhere else?
