So my initial assumption is that the bulk of the work would be in gaining and confirming that control and the rest would likely be "trivial" analysis of traffic through those gateways.
This seems like a big problem since there’s not much incentive, other than altruism, for most people to run Tor nodes, especially exit nodes which will draw a lot of unwanted attention from law enforcement.
On the other hand, intelligence agencies have a large incentive to control a majority of Tor nodes.
It’s also pretty telling that Tor was partially developed and funded by the US government.
Times were different then. The US was fighting wars to topple dictators and spread democracy.
Yet none of the above matters, what matters is the entire GOP been willing to cover for all off the above and worse, throwing out centuries of political norms to “win” and by doing so enable the worst president in a century to do all off the things above and worse.
This is a man who is a systemic risk to an already creaky system and I have a vested interest in the US doing well.
His inaction has led to a massive death toll, he overtly politicised a pandemic then let his family control where supplies went for political reasons.
The best thing the man could do for America is have a stroke.
I suppose there’s still two entrance nodes, one for each side. But unlike visiting the clearnet over Tor, neither side is aware of both at the same time.
