There were several Q references to use of back channels not labelled as such; use of comms via video games, Hillary's private server, Fiveyes (sp?), pseudonyms by key players through emails, HAM radio, distributed news media talking points and news media in general, Dem-only closed door impeachment hearings, SCIFs, MS-13/cartels (187s), sanctuary cities, foreign donation channels, cryptic/altered text, Ukraine corruption, courts/judges, medical, wars, disaster claims, multiple non-profit Foundations, social media, global warming hoax, Iran, China, Aus/NZ, GB, Germany, Italy, Israel?, Saudi royalty, NKorea, CIA/FBI, UN, NATO, speaking tours, book deals, immigration, movie industry, schools, US/foreign ambassadors, gun control, abortion, convenient (only to Dems) mass shooting events?, symbolism?, smoke signals (probably).
Some of those may be more implied and I might be stretching a few with a foil head warmer. However, I'm still less biased than the Leftist Enemedia.
Most, though, are paths discussed here in the past as channels the Left has used as beards to secretly peddle their corruption (message/influence/funding) throughout their network of “Destroy America” minions.
Others?
The last scene of Clancy’s SumOf All Fears was about keeping back channels open to stave off catastrophe. It’ was a conversation between a Russian agent and an American agent.
Interesting that Q would say that soon after saying Clear And Present Danger, another Clancy movie.
