Things take time to unfold.
The battlefield needs to be shaped.
Just think about how many more people will be thinking and talking about this within the next few days. People that had suspicions for various reasons. Questions about various aspects of many of these events.
Always remember that the stage must be set.
American innocents should be worth more. This should be exposed by law enforcement or intelligence agencies so there is not another incident without every American questioning the left first. That will end false flags in a heartbeat and leave only real incidents.
This approach does not harm "the plan" just gives it a stronger reason to be carried out in the public mind.
