Tor is vulnerable to your so called ´global´ adversaries.
That is inherent to tor´s design.
And by the way, ¨global¨ here is of course vague and
misleading. It is just a matter of getting enough traffic.

I understand that there is no design that can counter traffic
analysis, but that doesnt excuse tor.
Tor is an ´anonimity´ tool that can be easily subverted by any
´adversary´ who collects enough data. That is part and parcel
of the very desing of tor. So, sayig that tor is vulnerable BY
DESIGN is a valid way of putting it.
The trick is, as I previously mentioned, to mention that
limitation...sometimes...and sometimes not.
Yes, yes. You have your papers. No, I doubt those papers are
read by ´ordinary´ tor users.

You do realize that given the politics of the US government
your claims are pretty shaky, no ? You are to be oh so
trusted...because you say so? Come on.
Extraordinary claims require extraordinary evidence.

It is a well known fact that the US government can
compel its subjects to brazenly lie on matters of so called
Extensive cooperation between american firms helping the
criminal activities of the US government has been widely
And you want people to believe that you, who are explicitly
working for the US military, have not been influenced by them at
Again, such a very very extraordinary claim requres very
And yet, there is no proof to be seen. Except your words.
