3 of 5 permanent veto-wielding members of the UN pseudo-Security Council are not signatories to the Rome statute. For US, Clinton signed but never intended to ratify it. Russia signed in 2000, but withdrew in late 2016 after it was preliminarily found to have run afoul in 2014 re: Ukraine. China and India never signed even. Of the top 10 most populous countries, only 4 are signatories (Nigeria, Brazil, Bangladesh and Mexico). At least 2/3 of the world population lives in non-signatory countries.
