>> The Biden diplomacy was through the allies to both sides behind the scene
I still stand by my evaluation: Biden’s team is very focused on how they look politically. Within hours of ceasefire, there are well-sourced articles describing in detail how smoothly they worked behind the scenes, even how they were much better than Kerrey and Hillary during similar fighting. This means that these people had enough time during the crisis to work with journalists developing the story.
This does not mean that they did something wrong, but it also does not mean that you need to believe the press releases.
