I don't think you should be downvoted, but the polio campaign was lying to citizens of other countries, not domestically, which I think is the crucial distinction here.
Eh, how about the reasons for the Iraq war, or the nice brochures the AEC gave the people of Utah about the innocent fairy dust raining down on them from the atmospheric Nuclear Tests in Nevada ?
This distinction is a bit shit. If US wants to portay itself as leader of the free world, it needs to stop acting like a them and us set of rules.
