Or what? The Trump administration has already set the precedent that things signed into law mean nothing. If Trump wants to sanction the ICC then that effectively means the rest of the world is no longer going to treat the US as a friendly, or even neutral, country.
You can certainly tell the ICC you are not war criminals, but if you do that through strong arming instead of through presentation of evidence then you are one step short of straight up admitting you are a war criminal or intend to perform acts that would make you one in the near future.
You are a shit stain, Donald Trump, and no amount of crying like a whiny little bitch is going to clean your sheets. I hope you enjoy the smell in your own bed, which I guarantee you will be stuck in within 365 days.
Because most CEOs are wholely incompetent and don't know how to run a successful business.
