content: The government has set TOR as enemy number one.  The FBI and NSA have spent billions of dollar researching and subverting TOR.  It's the greatest threat to them.  According to the Snowden documents the NSA runs at least 50% of the TOR nodes in the world.  When they want to trace an individual they use a second network of computers to flood all the non-NSA TOR nodes effectively knocking all the non-government controlled nodes off the Internet.  This makes the only working TOR nodes government controlled nodes.  Then they simply trace the activity of whoever they want to trace since they own all the nodes in the chain. This tactic is undefeatable as the only thing the government needs to succeed is more money, and the government has unlimited amounts of that thanks to so called "liberals" who relentlessly advocate for more government power and higher taxes.
