Can a 3rd party decrypt static Diffie Hellman?
I am wondering if static DH allows for the same sequence of 3rd party decryption as RSA?


Yes, if a third party learns the server's (or the client's) DH private value, they can recover the DH shared secret, and thus recover the premaster secret, the master secret and thus the traffic keys.

This is true for both static and ephemeral DH.  Of course, with ephemeral DH, both sides are supposed to discard their private values immediately after using it (and thus the window of opportunity for the attacker is less).  With static DH, this is obviously not possible (as the server will use the same DH private value for the next negotiation).
