Very few countries are active war mongers, so it might actually be possible to assemble a bloc to try making US accountable. It probably wouldn’t be possible to go after prime perpetrators, but it might be possible to at least start extracting low key figures and put them on trial in a way that US cannot interfere with.
Thanks to US we already know how to handle this - there is a plenty of secret locations in various different countries where the perpetrators can be safely tried and then handled according to the sentence.
I doubt the US would take their citizens suddenly disappearing in a country very well either, and keeping it hidden would be difficult. Maybe you could secretly convict a soldier who desecrated corpses or something, but people like Gina Haspel would be nearly impossible without ramifications.
