What's good for the goose is good for the gander. The US is acting to impose sanctions on individuals with no direct ties to it by using its legal authority over American entities. The reason the US wants to do this is because the ICC is seeking to impose its legal authority over individuals whose state has not joined the ICC with novel legal theories and using its legal authority over ICC states. If the ICC had remained in areas where its legal authority is clear and not disputed, its judges and prosecutors wouldn't be facing this issue.
