In Trump's video last night it's clear that he was speaking to a script and it's kind of clear that he had been more or less ordered to deliver it by various of his staff, family etc. So in that sense I think the short-term danger has passed: Trump went to the brink, enough people were scared by what that led to (even though it was pretty clear what it would mean and has been for ages!), and he's been reeled in. Given that he's been allowed to tweet for around 24 hours, and has only sent that video, I think it's going to end there and that this will be enough for Republicans to decide that he's "learnt his lesson".
But this should not be nearly enough. Trump isn't a naughty schoolboy, he is a President who incited a riot that led to damage to the US Capitol. A video and a short ban from social media isn't going to cut it. Actions should have consequences. Trump himself spoke in the video about how this is a nation of "law and order". That means him, too. The 25th Amendment, and Impeachment, exist precisely to protect the US from actions like this. That Amendment in particular is meaningless if it's not invoked at this; I can just about understand that Republicans remain wary of taking action against the man who only a few months ago showed that he had the tacit support of around 75 million voters, but Law exists to protect the country from itself, from its short-term political whims, and it really must be invoked here. If instead there's a message of tolerance, then what protection is there from any future President who plays from the same rulebook (only with more competence)?
