Well if what you have said is true then you are to blame for the creation of the chaos gods. Also I would like to Clarify that unless you have done extensive research into warp technology then you cannot block Chaos signatures.

The God's themselves do not have a physical form and thus cannot be killed although they will never actually show themselves rather send daemons and the like. As for your remark about you psi units I really can't say how they would stake up against a regular Daemon of chaos as Daemons utilize the warp not psi. Psi is only used to gain access to potential host bodies. :/

But it sounds to me like your sole purpose is to belittle other nations and that isn't cool.
