W&W is a Q reference to military intelligence vs. C_A. He has inferred that MIL / NSA has been engaged in this conflict for a while. The Snowden refs, the Snow White refs, those trace back to the era of 2010 and the "hacked" Hilary server, which supposedly outed the identities of C_A assets in China. Those guys were executed by the Chinese. It is not clear who started it, or if that escalation was just payback for something else.
My belief is a serious rift began internally after 9/11. Lets say one side wanted to keep the truth hidden and the other side didn't. But that is speculation.
