Every government has some form of a propaganda team behind it. Some directly in the government, many behind the parties/companies in power. Really anyone who benefits from the way the government operates has a reason to push propaganda at some level.

However, suppressing the opposing view is the problem. If the viewpoints are both expressed, one can expect some level of truthiness(tm) to come out. And frankly, someone's got to defend what the government's doing, b/c sometimes their actions aren't completely corrupt or nefarious.

As for the US, I'm hoping the Net will eventually dissolve the b.s. legitimacy of the old press core, who've got too much to lose to rock the boat very much.
