Mike Waltz throwing a fit about the US sanctions on the ICC: "We could see a situation where they even go after American leaders. We never signed up for it." The "we never signed up for it" is the tell. He means the US never signed up for consequences. The ICC doesn't investigate countries that cooperate with it. It investigates when national systems fail to prosecute their own war crimes. Waltz is basically admitting the US doesn't trust its own system to handle accountability, which is exactly why an independent court exists.
