Individual tribunals are actually better at addressing the specific situation.  The idea of "universal jurisdiction" becomes dangerous when it is regarded as a blanket solution. For example, after the Spanish Civil War, post-Franco Spain decided to avoid trials for the sake of national reconciliation that enabled it to become a peaceful democracy. Setting a precedent of universal jurisdiction for punishment unnecessarily precludes better reactions more tailored to the specific scenario.1 (See opposition argument #3 for elaboration).  1 Kissinger, Henry.
