If you presuppose that the world is being run by a unified-in-purpose dark entity, things will never quite make sense.

It is better to presuppose that there are many different people, each with a different idea of how the world should be, and who work together where they can, but fight for power otherwise.  So what George Soros wants differs from what Hillary Clinton wants which differs from what Klaus Schwab wants which differs from what Jacinda Ardern wants, etc.

What happens is that certain bad ideas become popular, certain good ideas become forgotten, and there is a lot of what the courts came to call "parallel action" that isn't actually overt collusion.  For example, the neocons become focused on money laundering and over time neglect to be concerned with actual wartime strategy, and so all the wars are lost. But nobody got together in some dark shady room to decide to lose the wars.

Our human minds are very limited, and it is easier to model reality as a small group of intentional humans, rather than the insanely large group of intentional humans that actually exists. That leads us to these shortcuts, to believe a deep state or global jewry is somehow organized and intentional and has a "plan".

Freeing Assange was just a political pressure move. Assange killed or jailed vs. Assange free makes no difference to anybody in power. They only wanted to kill him because they were mad at him, and to send a strong message to others not to behave like he did.  I think that strong message has been sent well enough, so keeping him longer didn't really matter, except to foster more distrust and antagonism against government power.  So freeing him worked in their favor as the masses hopefully won't continue to harbor as much hate for the power of government. 

 People kinda live in their own bundles of narratives  ..
