I beat one of these guys in the Irish judo championship way back when I was a yellow belt and he a black belt. Rough northside inner city lad trying to rough up a TCD senior freshman, what? When we meet up at airports, for example, we exchange pleasantries (*) but we never we never talk about it. It would be crass.
These guys confer accolades on each other. They won't get a belt any other way.
A commmon theme was the obsession with power, irrespective of the scope and influence.
(*) apart from that coup in IJA.
