'A series of “humanitarian pauses” to fighting in Gaza are due to begin on Sunday, to allow hundreds of thousands of children to be vaccinated against polio.'
So, in August 2024, to help WHO etc get Gazan children vaccinated, Israel stopped fighting and agreed to a ceasefire, even while Hamas still held Israelis captive in terrible conditions.
So, as I said upthread, Israel facilitated (that is, helped it to happen) the polio vaccination campaign.
Some posters seem to struggle with the meaning of 'facilitated' as well as the meaning of 'genocide'. It's hard to know if this is ignorance, wilful blindness or disingenuousness.
