The sickest confirmation of this point was the recent revelation that the CIA ran an operation to verify Osama bin Laden's location by gathering DNA samples through a false-flag hepatitis B vaccination programme. As James Fallows notes, American officials are defending this operation, not denying it.
This is despicable and stupid.
All over the world, poor people resist vaccination campaigns in the belief that they are part of a plot by powerful authorities to take advantage of them. The CIA operation in Pakistan turns these fears from crazy conspiracy theories into accurate and rational beliefs. But what's really tragic is that Pakistan happens to be at the epicenter of a crucial ongoing vaccination programme: the worldwide campaign to eliminate polio, which has been hampered by opposition from Muslim clerics. As it happens, the only countries in the world where polio is still endemic are Nigeria, India, Pakistan and Afghanistan, and "persistent pockets of polio transmission in northern India, northern Nigeria and the border between Afghanistan and Pakistan are the current focus of the polio eradication initiative."
