@dowieAlright then dowie, sleep has been had so I'll be coming back at you today with something to blow the whole shebang wide open! Bear with me brother.
I can find nothing more than articles regarding various Israeli Lobby groups affiliated with Israeli officials
who are pushing the IHRA definition on multiple governments. Unfortunately I cannot find a source I don't consider to have some possible bias.
We know many agencies across the world throughout history have used similar tactics to push their agendas so there is plausibility, and in this case the lacking of direct "contact" from their governing body with the IHRA definition feeds the potential for the same suspicions, ironically. And having these suspicions of a countries motives is not caused by an inherent racism, history has taught us to be suspicious of dubious actions by many countries.
