To be clear, I don’t have any dual citizenship, so I’m ineligible for a direct answer.
But it’s a huge question for my cousins, who are US citizens by birth, but lived in Israel after my aunt emigrated until their majority. Of the three, two live in the US year round, though they visit their mother semi-frequently. The third came to the states to go to college, and after returned to Israel and has fundamentally not left. He is all but certain to renounce his US citizenship, and I know his kids pretty much consider themselves 100% Israeli.
Of my other two cousins in the states, well, I think the middle cousin would renounce her Israel citizenship, mostly because she gets more support here than she would in Israel and isn’t particularly close with her mother (mother/daughter issues). My eldest cousin I think would be close to 50/50 - his business is here but he’s very attached to his mother, and I could see him go either way.
A very ironic twist though is all three are heavy Trump supporters, based almost entirely due to his stance on Jerusalem and related issues. Despite this, his administration is going to throw them under a bus on this issue, and I’m tempted (not gonna do it, but tempted) to throw this in their faces if it goes into effect.
Actually, now that I think/type about it, I’m pretty sure the youngest cousin (they’re all older than me though) has already renounced his US citizenship, when he was working for then new-to-the position President (largely ceremonial) Reuven Rivlin.
