I don't think it's so much that the deep state now works for Trump, but more so that Trump could be part of the deep state.

We all know where in the middle of an information warfare, with psy-op on top of psy-op. 

Would it be far fetched for the deep state to partake in a decade long plan to psychologically subvert the population that is most distrustful of them, by building up the Trump narrative?

Personally, I don't think it is. 

Just like I don't believe it to be far fetched that Trump could be a threat to the deep state's power structure, forcing their hand in attempting to murder him.
