Do the terrorists understand that polio is a debilitating and contagious disease?

Re: Do the terrorists understand that polio is a debilitating and contagious disease?

Does that give one justification to block the polio drops campaign and let aggravate the polio crisis? What about dozens of polio health workers who were shot dead?
What CIA did was the best for their country, why are we incapable to do the best for ours??

Honestly I think we even dont realize how harmful it is four our generations to let polio escalate rather than crying over what CIA did.
