While Donald Trump is in court, House Republicans rejected their presidential nominee’s bad land-for-peace deal in Ukraine

In chaos theory, the flapping of butterfly wings can cause a hurricane on the other side of the world. This weekend, Ukraine experienced a butterfly moment. Donald Trump’s efforts to conceal the fact that he bought the silence of a porn star before the 2016 election landed him in court, facing charges that preoccupy him enough for congressional Republicans to reject his policy of prematurely ceding territory to Russia in return for peace in Ukraine. Kyiv will now get billions of dollars to buy the weapons crucial for it to defend against, and push back, the Russian advance. It is fitting that Mr Trump’s divisive appeasement has been defeated – for now – by a bipartisan defence of democracy.

The presumptive Republican nominee had, in an election year, counted on using his mendacious, inflammatory rhetoric to further convert his party into a truth-denying sect prepared to abandon the rule of law for the rule of revenge. Instead, he is required to attend every day that the Manhattan court is in session, for a trial expected to last at least six weeks. The proceedings will be closely followed around the world. But they will not be televised. It will be a circus, but without its ringmaster. Deprived of the camera’s attention, the former president won’t be able to bully Republican lawmakers or rally his followers so effectively.
