Kenya has single handedly killed ICC.
In what way is that? As far as I can tell, the ICC is quite busy nd will be quite busy for a long time---overloaded with work, in fact, and almost all of it from Africa. What's more, one can count on Africans to keep sending their people there---former leaders, rebels, and the like. As an example, note that while Museveni has been a leader with the anti-ICC vitriol, he was quite happy last year to quickly hand over Ong'wen.
In my view, the Kenyan fiasco has actually led to lessons that in the end will lead to a strengthening of the court.
