“”Participated?” So far, I don’t know what that means.”
To me it means that those countries ALL KNEW what was going on and for reasons they’d like to not talking about (ahem, immigration), they figured it was best to look the other way.
They all knew for nearly 2 decades as Hamas took international aid and built tunnels and stashed weapons and rockets inside and underneath UN schools, clinics, food banks etc. UN didn’t care.
Trump cut off aid to UNRWA he knew what was going on. They called him cruel, racist etc. Biden hastily reversed the decision like he did most of Trump’s policies - for spite. And to restore the flow of graft to the cronies.
