So first; your comment sounds passive aggressive. You can argue/ discuss without it. If not, I’ll just block you.
I appreciate the sources, never knew it was thanks to his father - that Biden is a pro-Israel/ Zionist. However this does not particularly show that defending Israel is a “promise to his father”
Like the other comment state:
Biden's primary stated reason for defending Israel is a promise to his dying father
In none of your articles does this come up. Only that his father is the reason of him being pro-Israel.
I know very well Biden is a pro-Zionist/ pro-Israel. You can check my comment history.
EDIT: so your sources and your comment doesn’t “answer” my question at all. It just shows he became a pro Israel because of his father. Not about him promising his father, he will defend Israel.
