Bill's question, why?, is the crux of the thing. If there is an answer, I don't think it lies with Iraq's WMDs. Kelly was one of our most brilliant microbiologists, global class, at 40 heading the bio-warfare division at Porton Down. Long before Iraq, with close working links to Washington and the Middle East, Kelly was one of the few people in the world to know who had and who was developing not only bio weapons of unimaginable evil, but the antidotes and antigens to everyone else's. In his head was information that could destabilise entire regions. If there's a 'why?' I think his bio warfare knowledge was it.
Kelly's ordeal at the hands of a thuggish and brutal Commons select committee, the sneering insults, the bullying and bared fangs of hounds at the kill exhibited by semi-feral Labour MPs certainly tipped him over the edge. In that state, no-one could be sure what he'd reveal - not about Iraq, but about some bio-warfare secrets of far greater impact to sensitive nations. And for that I think he was killed.
As to the 'who?' only the Israelis have the skills and resources to maintain murder squads around the globe of this calibre to murder dissidents. And I'm sure they did it without any knowledge on the part of HM Government whatsoever. Perhaps they used a cannula and bag to drain his life's blood. I don't think we'll ever know for sure. And for their own ends or those of a third party, who knows.
I think the lesson is clear to all of us; the world's a very serious and scary place, with nations playing for very high stakes, stakes against which the value of a single human life is nothing. And that unlike the UK, there are many nations who view selective murder as just an extension of Statecraft.
