It seems likely the ICC will issue an arrest warrant for Trump in the coming years. I see all their recent moves as a signal they want to distance themselves from the US so they can actually issue that warrant.
There are quite a few reasons that should happen, but I won't hold my breath. And I that issuance really won't do anything worthwhile, except be a footnote in a history book.
I don’t think there is any way in hell the US is going to be welcome back on the world stage as a partner to any of their former allies again unless among many other things they put themselves under the ICCs jurisdiction.
Trump's life-span is likely to not be a very large number of years from today given his age, and systemic health problems.
SO I expect ICC would find other people, e.g. Marco Rubio and Pete Hegseth, who are helping to commit these areguably war-crimes in the Pacific and Caribbean seas, the missile strikes against civilian non-US vessels.
