If OBL needed dialysis twice a week dialysis before operation enduring freedom do you think he would have survived skipping dialysis on the run? Actually nowadays you dunno who's unreliable and reliable. Where did you hear a dead muslim buried at sea huh? Oh we have the DNA! Yeah right....
bin laden spent the last year of his life in Iran. They also sheltered members of his family. zawahiri is in Iran and travels back and forth to Pakistan rarely, unless there is something he does not trust a courier with.
They never had bin laden’s DNA. What they had was a DNA sample from his mother or some other family member. The DNA they claim was bin laden’s was his son’s.
It retrospect, there never actually appears to have been much evidence to the claim. (See this 2006 Washington Times debunking.) Peter Bergen, who interviewed bin Laden in 1997, described him as “in excellent health” and saw no evidence of kidney trouble or dialysis. Journalist Robert Fisk who interviewed him three times made no mention of it. Bin Laden’s own doctor, who was arrested in Pakistan in 2002, had given the al Qaeda leader a complete physical and treated him for a back injury but later told reporters “his kidneys were fine.”
