Honorable people/states/governments, value honesty, justice and credibility. It is a "Western" thing.  The handshake was enough for Honorable people to trust the others word and to keep their promise. It is laughable that the ICC; as a sophisticated institution, relying on the innate sense of justice of its members, should  think that an ANC Government should be required to do this.  A true test of proper values against a corrupt and deceitful government.
