I think that's a good point

If you tell a lie big enough and keep repeating it, people will 
eventually come to believe it. The lie can be maintained only for such 
time as the State can shield the people from the political, economic 
and/or military consequences of the lie. It thus becomes vitally 
important for the State to use all of its powers to repress dissent, for 
the truth is the mortal enemy of the lie, and thus by extension, the 
truth is the greatest enemy of the State.
