The story is , and i remember reading about this in Nexus magazine in the 80's
Flouride was (allegedly) developed by the Nazi's in WW2 as a control mechanism, its been said its ingestion atrophies that part of the brain that makes you rebelious to authority, that the Nazi's added it to the Polish water supply prior to invading and then rolled into Poland, virtually un challenged.
At the end of WW2 the research data was taken by the allies who in turn started using it on their populations, and that there hasnt been a social revolution in any population thats been using it since......
Personally i cant tell you if thats the truth or not, you'd need to research it yourselves, there is lots and lots of stuff to read though , it will take you a month of sundays to get through half of it.
Have fun
