In Israel, there is the Law of Return, which states that any Jewish person (or one with Jewish roots) is allowed to make ‘Aliyah’ and immigrate to Israel, becoming a citizen.
I will add that making Aliyah doesn’t make you eligible for the National Team, you still have to live in the country for 5 years as per FIFA rules.
Without going into politics, I think that implementing it would add a lot of realism to saves in Israel, as looking for Jewish players abroad is a big part of scouting in Israel, as the foreigner limit is very strict.
I know religion doesn’t have anything to do with FM and it shouldn’t, maybe it can be a hidden attribute for real life players, with newgens outside of Israel given a chance to ‘spawn’ with an Israeli second citizenship depending on the country’s Jewish population percentage.
Once again I am asking people in the forum to not go into politics, let’s keep this discussion civil…
