It'll never happen. He is not losing any sleep over this. It's just a fantasy about retribution.

The United States doesn't recognize the ICC. So there's nothing for him to be referred to. If the ICC wants to create a legal case against him, all the US has to do is point at Xi Jingping and is ethnic cleansing programs and ask why they haven't brought a legal case against him and tried to extradite him.

Everyday Americans would not tolerate it. Remember that while many don't like Trump and for good reason - me included - it would be viewed as a violation of American sovereignty which would not be tolerated. I would oppose it myself even though I think he belongs in jail over January 6th. But he'd belong in American jail, tried in our courts, under our legal system.

I also have to add it is always interesting to hear the things people proclaim to care about. I don't think everyday Americans even if they know about this alleged[1] double-tap, really care much or even think about it at all. I know I don't. Has anyone brought a case to the ICC? I know that South American countries referred Maduro to the ICC. :)

[1] It seems clear that it happened, and I'm not disputing that. But I say alleged simply because there has been no prosecution that I'm aware of. If there's a better word choice than alleged I'd be happy to use it, it was just the one that I thought fit the sentence best.
