The United States Government will fail because even if they were to significantly disrupt the Tor network we'll pull out the Zero Knowledge Proofs on them. We have the crypto and technology to build a super resilient Tor replacement that they cannot do a single thing about. Tor is antiquated and I personally hope they take it out because it's replacement will be 100x better.
Lots of people around the world depend on the anonymity of Tor today and having the Government take it out, whilst indirectly kick-starting the next generation anonymity network is all and well for me and my armchair, but it's going to be life threatening for many.
Until this 100x better solution exists Tor must be kept running at any cost, many lives depend on it.
