That he didn't was repugnant and a dereliction of duty, but even if he had, do you honestly think that mob would have done anything different? People in groups don't think normally, that's pretty well studied and established; I don't think it would have made one whit of difference.
But he should have tried; I'm surprised someone didn't even tell him to just for the optics of it.
White house staff and Trump's family members were urging him to do something while he was enjoying watching the show unfold on TV. I'm unsure of where you live but the truly surprising thing is many people in the US aren't aware of this.

But Trump did call for peace twice on January 6. The tweets are publicly available. The idea that he did not is a conspiracy theory similar to the very fine people hoax.
No. This is false. Trump specifically called for law and order at the protests twice on Jan 6th.
More than 1500 people were charged for the Jan 6 riot. Trump has indicated there will be exceptions.
