There was Islamist opposition to polio eradication campaigns before anyone in the West was sure that Osama Bin Laden was in Pakistan. (That's why it surprised me that vaccination campaigns were used as a ruse for verifying his whereabouts, but apparently Bin Laden's personal crazy ideas didn't include opposition to vaccination.) It's not entirely a coincidence that even before anyone heard about Bin Laden, the last few places on earth with endemic polio were all places with militant Islamist movements. Personally, I would rather have my children live long healthy lives, no matter whose idea it was to invent vaccines or to use a vaccination campaign as a pretext to find an international fugitive, but logic doesn't always appeal to people who are already making excuses for being illogical.
