[Netanyahu has mentioned this man as key before. So what's the bet that he was behind this killing. Note the short excerpt below. Jan]
Why was he targeted?
By Paul Adams, BBC Diplomatic Correspondent
As head of the ministry of defence’s research and innovation organisation, Fakhrizadeh was clearly still a key player. Hence Benjamin Netanyahu’s warning, two years ago, to "remember his name".
Since Iran started breaching its commitments under the terms of the 2015 Iran nuclear deal, the country has moved ahead rapidly, building stockpiles of low-enriched uranium and enriching to a purity above the level permitted under the deal.
Iranian officials have always said such moves are reversible, but developments in research and development are harder to eradicate.
"We cannot go backwards," Iran’s former ambassador to the International Atomic Energy Agency (IAEA), Ali Asghar Soltanieh, said recently.
If Mohsen Fakhrizadeh was the key player Israel alleges, then his death could represent someone’s effort to put the brakes on Iran’s forward momentum.
With the US president-elect, Joe Biden, talking about taking Washington back into the deal with Iran, the assassination could also be aimed at complicating any future negotiations.
