I wouldn't compare Operation Himmler so much to 9/11, but rather to Operation Northwoods (which never got carried out in the end). A mildly interesting read on the issue of tyranny disguised as democracy is Muammar Al Qaddafi's
The Green Book, regardless on whether he followed the ideals presented in it himself.
On contemporary issues in the US, I can strongly recommend [URL=

I don't think 9/11 was staged by the government, but it certainly helped them to start a war they wanted to start anyway. I believe it's more likely that really a misguided Islamist extremist sub-group was behind the attack or if it was a conspiracy, that the government was not directly involved. I believe the culprits in the case of a conspiracy to most likely be people in the weapon industry / powerful warlords / drug lords (either US or Iraq/Afghanistan based, both or wherever), who of course would make huge profits from any war at all. One or two people inside the government might have been involved, but I find the idea for it to principally have been a government conspiracy rather unlikely to be true.
That being said, I don't think the US government is on the right track, but I believe that the average US citizen is to blame for that. They don't care too much about political issues, especially if it's about countries outside the US. The wealthy, on the other hand, do care a lot. And that's the whole reason why the government acts on their behalf. The general public can be sold the idea that what's good for the rich is also good for them only because they don't really care themselves, they'd rather put their trust in somebody else than educate themselves about these issues and form their own opinions. As long as the general public doesn't care, a democracy cannot work properly. Many First World countries besides the US have the same problem, but with the US being so militarily powerful the issue is much more serious there.
Of course (imo) the proper way to fight terrorism is to educate the people and help a country fighting against their terrorist groups themselves, instead of invading it. What has been carried out is a war that's mostly in private interest of the US, is pretty ineffective in fighting terrorism, but it helps sell the idea that these wars are good and just to the general public.
