Nanotechnological solutions to anti-American sentiment

Of course, this is a lot easier said than done; so I was thinking of how such nanobots could possibly work. Some ideas I've had were:

• "Simple" ones could modify the subject's neurology to respond to a simple signal, otherwise undetectable or unexceptional (say, flickering colours with a certain frequency range), and then trigger neurochemicals putting the subject into a state of hypnotic suggestibility. The signals could be coded into innocuous programmes with pro-US messages (i.e., that fulfilment can be achieved through eschewing radical politics, working hard in the Nike plant and using your earnings to buy consumer goods and watch Hollywood movies).
• Alternatively, the state induced could be one of mystical experience. (Scientists have recently discovered the neurology of mystical experience, and that a mystical experience is just a normal experience content-wise, only with a "THIS IS IMPORTANT" flag set; the same flag is set in normal experience during crucial events, such as parent-child bonding.) Which could allow spiritual movements and cults to be engineered on the fly. The Church of Mickey Mouse, anyone?
• The mystical experience flag could be used more practically to induce the belief that a certain figure (say, George W. Bush) is speaking pearls of numinous wisdom. Though this may be best used on domestic populations to shore up public support and unity.
• The idea of infantile regression and parental binding lends itself to other possibilities. If the targets could be induced to feel that America is a benign, if stern, parental presence, rather than an imperialist exploiter, their attitudes could be turned around without any change in US foreign policy. This could be achieved by triggering a regression to an infantile state with signals in materials bearing symbols of US influence.
• Moving away from embedded signals, infantile states could be useful in other ways. If the people of the third world could be made to feel a sense of wide-eyed wonder about the special effects of a Hollywood blockbuster or the bounce of a Britney Spears song, they could be put onto a more consumeristic path, and one less inclined towards tribalism, nationalism or militant ideology.
• Of course, induced states of consumerist fulfillment among the world's poorest could lead to social upheaval; the nanobots would have to also have the effect of inducing a Prozac-like calm whenever anger, frustration or non-fulfilment is experienced. Thus the targets could be made like the dull-witted yet good-natured peons in an old Disney animation; seeking consumerist cargo-cult fulfilment, but too docile to kill for it.

How could the nanobots be delivered? Through USAF airdrops into water and food supplies, by covert insertion through CIA stations (or even compliant corporate sales branches, if the parent company is told they will benefit from improved conditions in the territory), or they could even be made self-assembling, with one or two nanites dropped into an area rich with raw materials to build more.

These were just some ideas I've been thinking about; they'd probably be more useful from a fictional perspective, though those reading this through Echelon may well find practical uses for them...
