You expect competence and ingenuity from Israel’s Mossad spy agency, so it’s no surprise it knew Hezbollah, the Lebanon-based Islamist organisation, was planning to replace the mobile phones of its planners and commanders with old-fashioned pagers. (One-way pagers cannot transmit, so do not reveal the holder’s location.)
More impressively, Mossad found the information early enough to use it. Its operatives quickly turned to an obscure Hungarian firm called BAC Consulting that manufactures pagers under licence from a Taiwan company called Gold Apollo.
Gold Apollo’s founder, Hsu Ching-kuang, denies it made the pagers used by Hezbollah, claiming that BAC Consulting had bought the rights to manufacture its pagers in Europe.
"The product was not ours. It was only that it had our brand on it", Hsu said. "We are a responsible company. This is very embarrassing." Indeed.
Now come the speculative bits. Was BAC Consulting a front organisation set up in Budapest by Mossad?
That seems likely, because sabotaging 5000 pagers is an industrial-scale operation, not easily hidden. It is not something that can be done by three spooks working in a garage.
And how on earth did Mossad persuade some senior Hezbollah officials to order 5000 Gold Apollo Model AR-924 pagers from a dubious Hungarian company? Hezbollah will be tearing itself to shreds as it frantically hunts for the traitors, and some of its senior officials will be facing ruthless interrogations and probably even torture.
Speculations aside, the rigged pagers were all delivered to Hezbollah a couple of months ago and have been in daily use ever since.
The obvious question is: what was it all for? The answer to that lies in another question: why so many?
Normal Mossad assassinations target one or two key figures in militant Arab organisations. There seems little point in targeting thousands of mid- and low-level officials, all of whom will automatically be replaced by their immediate subordinates.
Unless, of course, you want to take out as many as possible of them on a single designated day.
The technical brilliance of the Mossad operation was not in how the pagers were manufactured nor in the way the explosive was disguised or concealed.
It was in the fact all 5000 pagers, widely dispersed across Lebanon and nearby countries, could be detonated simultaneously by a single coded signal.
That is exactly what the Israeli government would want to do on the day it finally launched its long-threatened invasion of Lebanon to "destroy" Hezbollah.
True, such an operation is unlikely ever to succeed.
After 11 months of fighting, the Israel Defence Force (IDF) has not even managed to destroy Hamas, a far weaker foe.
But for Prime Minister Benjamin Netanyahu’s government, which cannot think of anything else to do, attacking Hezbollah is an almost irresistible displacement activity.
If he finally decides to go down that road, then thousands of pagers exploding and killing or maiming thousands of Hezbollah’s key cadres on the first day of the attack would make perfectly good sense.
So why have the Israelis jumped the gun?
According to their own leaked explanation, it was because they thought Hezbollah was about to discover its pagers had been sabotaged. Use them or lose them, even if using them without an accompanying invasion is a far less effective action resulting only in a few thousand shredded hands, faces and groins.
To maximise the damage, Mossad reportedly sent a message alert to the pagers less than a minute before the actual "explode" command in order to ensure as many Hezbollah commanders as possible would be looking at their pagers at just the right time.
However, the pagers that stayed in trouser pockets did almost as much damage to stomachs and genitalia.
On Wednesday afternoon, the Israelis blew up several thousand Hezbollah walkie-talkies that it had also rigged to explode on command in a separate, probably much earlier operation.
Most walkie-talkies were in storage and would only have been issued if Israel actually invaded, so there were few casualties from those explosions.
The whole thing is just a footnote in history, really, though a fascinating one.
Most of the victims were actual combatants, for once, and the only message it sends is Israel is not yet ready to invade Lebanon.
Whether it ever will be ready remains to be seen, but doing so without crippling Hezbollah’s communications first would be a very big mistake.
