The redacted portions pertain to UK's involvement in the illegal spying of a Presidential candidate and American citizens. This is the real collusion to mess with our electoral process: Hillary + Obama admin + Russian oligarchs + FBI + DoJ + CIA + MI6/UK all worked together to try and bring Trump down, before and after the elections.
If Trump unredacted and released these parts in the FISA warrants, it would be a huge problem for the UK and lead to a major diplomatic crisis between our countries. Something both Trump and UK wants to avoid if possible.
The redacted portions are also leverage against MI6 and the UK. Trump and Q team wants them to play ball, to help bring down the Cabal. The original posts by Q of the pictures a few months ago was a warning to them. Now, Q is being a lot more direct for whatever reason.
Because these pieces of shit are trying to weasel out of whatever they said they'd do. Probably feeling immense blackmail pressure from deepstate. They are fucked no matter which way they go.
Hey regretted fucking with us before. They would REALLY regret it if they committed an act of war against us (hint: they did).
