A tactic that takes 80 million people as hostages. Just as a side note: you can not give back Iranian citizenship (if that would be possible most Iranians in the West I know would do it). This concept does not exist. So even if you are the most western, fully integrated European which happens to have some Iranian roots you are still treated in a racist way because those new sanctions are so totally all-encompassing that you get fully subjected to it even if no practical connection to Iran exists.

You can totally "accidentally fail to declare" it. That's what I'd do living anywhere in Europe. For the most part, Europe won't put you in prison for ticking the wrong box on a form.

But it gets very difficult to never declare your place of birth, which, as mentioned by the OP, can be the same problem as having an Iranian passport.
