    any thoughts on this?

    It's totally true that the military people who invented Tor were
    thinking about how to create a system that would protect military
    communications.  The current iteration of that is described at

    https://www.torproject.org/about/torusers.html.en#military

    right on the Tor home page.

    However, the Tor developers also became clear early on that the
    system wouldn't protect military communications well unless it had
    a very diverse set of users.  Elsewhere in that same e-mail
    discussion, Mike Perry (a current Tor developer) alludes to this:

    https://lists.torproject.org/pipermail/tor-talk/2011-March/019898.html

    In fact, the best known way we have right now to improve anonymity
      is to support more users, and more types of users. See:

    http://www.freehaven.net/doc/wupss04/usability.pdf
      http://freehaven.net/~arma/slides-weis06.pdf

    The first link is to a paper called "Anonymity Loves Company", which
    explains the issue this way:

    No organization can build this infrastructure for its own sole use.
      If a single corporation or government agency were to build a private
      network to protect its operations, any connections entering or
      leaving that network would be obviously linkable to the controlling
      organization. The members and operations of that agency would be
      easier, not harder, to distinguish.

    Thus, to provide anonymity to any of its users, the network must
      accept traffic from external users, so the various user groups can
      blend together.

    You can read the entire (ongoing) discussion about government funding
    for Tor development via

    https://lists.torproject.org/pipermail/tor-talk/2011-March/thread.html
