This is just a thought experiment. Something about this story doesn't add up and seems too coincidental.
Iran doesn't have capabilities of developing nukes. No one would help them, except China:

Assassination strange - Car not shot to hell (only driver side). Explosion not rigged to kill but to slow down car. When have you seen an assassination whereby the vehicle was not completely destroyed, and an occupant was allowed to be taken to the hospital to die? Seems like an incomplete kill.

Plus, Soleimani was killed with a precision missile. Israel and Arab states all have access to that upon request with the US.
Theory:
Nuke scientist abducted, not assassinated. Expose Chinese nuke assistance, allows international pressure on China?
Defected.
reported like this: it was 3 bullet proof vehicles. the explosion took out the rear one, then a hit squad had a shoot out with the body guards, then apparently dragged the dude out of the car and shot him dead. who knows what is real.
They showed him in a coffin. His body was bundled up to the chin in a puffy shroud and his head also wrapped around, so really we just see the face.
Not that I am aware.
Very possible
It will be years before we know the truth. If I had to guess, he was abducted. If you wanted to kill him, just blow his ass up, leave nothing behind but scraps. Why even take the chance of botching it, use a missile. Defected seems possible as well.
Defected. The car wasn't shot up. Just 3 in the drivers side front window.
