Providing the polonium?
A common assumption is that Arafat died of AIDs, but if it can be proven scientifically that polonium was involved, it would be very interesting. But since Russia was involved in another polonium scandal, involving them in this investigation will only detract from its credibility.
With Russia and France involved, it would be like Al Capone and Lucky Luciano performing the same test on Jimmy Hoffa’s body if they could find a small piece of it somewhere!
Prediction: France and Russian “Scientists” find polonium in Arafat’s body!”
