political is..sorta true. the point of these international legal bodies was to maintain and enforce a world order dominated by western powers. it was not about promoting justice (albeit sometimes that happened.) the selective application of enforcement and investigation have reduced the ICC to little more than a tool of neocolonial rule.

the rome statute itself contains provisions that limit its reach. article 98 precludes extradition, which has been abused by the US to prevent US nationals from being tried.

in short the ICC is allowed to go after western geopolitical rivals, however going after an ally whos committing genocide is a bridge too far; they will be shielded. for example: the US pressured its allies to refuse to refer any activities in Afghanistan to the ICC and largely succeeded as its allies form the dominant half of the UN Security council. whats interesting here is the US seems so isolated this time as to have lost the ability to block the referral. perhaps a first in history.

I once had the honor to attend a lecture by a prosecutor of the ICC.

Out of all lawyers/attorneys/prosecutors/judges that I met in my life, that one was the one that I would judge to bet he most idealistic and justice motivated (admittedly based on my gut instinct); a very rare breed.

It's good that there are such institutions with a good purpose, staffed with good people. Bad faith actors - including war criminals - will of course claim agendas (other than bringing justice), deny jurisdiction etc. but it is a good starting point to have them. The next step is to strive to give these organizations enough "teeth" to execute.

The "individual bully" problem needs some addressing, a solution to that remains outstanding.
