The failure to include terrorism as a distinct crime was due to the inability to agree upon its proper definition.

The fact that Universal Jurisdiction exists in relation to serious international crimes does convey two important aspects of the global reality: first, that such individuals would be held accountable if international law was applied without regard to geopolitics, and second, that there is enough ambiguity about the reach of UJ that it inhibits such individuals and conveys an impression of de facto criminality.

It should be appreciated that this whole effort to hold leaders of states criminally responsible is a rather radical challenge to territorial sovereignty and a repudiation of the whole related ethos of 'sovereign immunity'.
