I have read periodic stories in the news, sob stories about how hard it is to renounce US citizenship. Including via HN quite recently.
My impression is that because the US tends to regard giving up citizenship as tax evasion, means that dual citizenship is a lot more common than in many countries who may not even allow it.
So, practically speaking, I wonder if the change you want might arouse opposition among other people than the ones you want to target.
Group 1 being people who are dual citizens with other countries than Israel, and their allies.
Group 2 being any entity that doesn't want to incentivize people to give up US citizenship and stop paying taxes.
Tactically, you might portray dual citizenship as being an Israeli/Jewish thing, but strategically it seems important to be clear on whether it's true. I don't know.
