I've searched and can't find anything online that Alexander Voronin was a known Zionist, a known arms dealer, or that he was grossly overweight. Can't find much of anything about him to be honest.
Vixen, what's your source for your claim that Voronin was grossly overweight, a staunch Zionist and an arms dealer?
edit: Ok, found some claims about Voronin, with the spelling "Aleksandr Voronin",which claim that he was a Russian arms dealer, the claims being made by Jutta Rabe and/or Christopher Bollyn (remember him?). Can't find anything solid though. Got anything Vixen?
