*gently bangs head on keyboard* The main female character's job was editing and revising old newspapers and publications to remove unwanted people, in much the same way Kerensky and Trotsky and dozens of others were removed from Soviet history.
That was the key of 1984; the Party controlled the past. What it said was history, WAS history. It constantly changed the past to be more favorable to it. However, while a government might be able to BLOCK unwanted websites it wouldn't be able to revise them (except Wikipedia of course :D) so one of the keystones of Party control wouldn't exist. Besides, that's what proxies are for...
1984 depends on a very Russian premise - that the worse things get for the common man, the more beaten down he becomes. However, 'nichevo' is not a usual attitude either among the US or the Brits; the worse things get the more likely that people are to look to create change in their own way.
In order to create a 1984-style society, you'd need all of these:
1) A single political party in control of all aspects of the government, including military and intelligence assets. THAT is nearly impossible, especially in the US. If Dubya were to declare himself King For Life he'd be out of power in a week and probably dead in a month; too many top people in the military dislike him.
2) A united proletariat who sincerely believes that the single political party is going to help them. Even a Christian President For Life would find this difficult to manage; there are too many religions flying every which way to please anyone, and even the ones who matched the PFL's would be hotbeds of 'treason'.
3) A clear, visible enemy that would convince every prole that the single political party is doing its job and let them become accustomed to a life of personal deprivation in order to fight the enemy, just as people went through in WWII. Terrorism won't serve in this regard; the enemies are too shadowy and I'm actually starting to doubt that Osama's going to attack the US again. His last attack was a PR disaster and removed a huge base of power from his control; why would he repeat a failure?
Truthfully, the US hasn't lost any civil liberties that we hadn't already lost long before - aside from a serious one allowing the President to send the militia of say Michigan to quell a disturbance in California. Most of the REAL bad shit was signed by Clinton, like the one allowing the Pres to declare martial law for as long as he wants to, over as wide an area as he wants to. FEMA is not our friend. The Patriot Act was mostly about letting the intelligence agencies do the same stuff they could do before 9/11, but do it a LOT faster. I'm worried, there's no doubt about that, but I'm hardly worried about the grey, colorless world of 1984. If there's one thing that being an insurgent against a militant religious government would be, it's not dull.
