I have no idea if it was intentional, but I can see it being so to determine how far they can really go without losing support. No western ally leader can go against Israel and still win elections, especially the presidency of the United States. That's just how it is, unfortunately. Biden has called for a ceasefire without any teeth and that's about as far as he can go without losing tons of votes from the "I stand by Israel" crowd which still has many adherents on the left, primarily "centrist" democrats which are still a huge part of the party. It feels like I saw the story on multiple outlets initially and not much since. It's still the political reality of how things stand. I really wish young progressives would continue their advocacy without saying they won't vote for Biden. I have no doubt that Biden is pretty centrist on Israel, but even if he agreed with the young progressives, he can't push too hard without letting trump take the white house, in which case he'd probably just give Israel nukes to wipe Gaza off the map.
