Biden is older than Israel, he was 6 when it was created, and he has said he will always support them no matter what because when he was a child his father made him promise to.
Elderly people often don’t realize how much has changed. In Biden’s eyes Israel will always be the victims because of WW2.
For him to accept that was generations ago and lots has changed, he’d have to come to terms with how old he is.
And if he could do that, he wouldn’t be trying to increase his record for oldest president ever.
