That is not fully true. I am not sure it is half true.
I get I should respect individuality but politics is built on group messaging.
The Sephardic are a small group with a different collective memory. The Sephardic are the majority in Israel.
There is a deep arrogance about questioning Israel’s intentions by the Ashkenazis in the US. A lot of that is a reaction to Netanyahu that has been simmering for decades now. Much of the problem is wrapped up in Netanyahu’s approach to American politics.
That does not mean the Ashkenazi in America should be so lazy about Israel’s security needs. Much of this discussion is full of second guessing and easy to reach misunderstandings of the situation by the American Jews.
