I agree with most that Edric pointed out.
Most importantly to add is, when and what was the reason he said this.
In Europe, many countries blindly supported Israel in the past as well, but now they show more nuance.
We (at least I) don’t really know if Biden’s view has changed in any way, but as you and Edric point out it has been over 30 years. Even a slight change could make this quote not relevant for his current stance.
I agree that Biden’s response shows very little concern for the Palestinians, which fits right in to any other US president’s view in the conflict. I think it’s deplorable, but I see a little hope in Blinken’s trip with the other Arab states and at least came to the conclusion for a fighting pauses.
As I understand it, the English and Arabic channels are very different editorially, with the latter being rather controversial and biased to the Muslim Brotherhood1. The English channel even wrote about the division themselves2.
This is something, in addition to that censorship exists in the west/everywhere (and arguably is favourable in certain forms), that should be kept in mind regarding Aljazeera. I must honestly say, I did not read more upon this, so feel free to correct or specify.
