Dual citizenship may still be possible even for countries that in general do not support such constructions, for instance regarding children with mixed background parents and other complicated situation. However, here I want to focus on countries generally welcoming dual citizenship (or not) – besides those that allow for exceptional cases.
The special friendship that exists between modern Germany and Israel makes it logical and should make it possible that all Israelis who want so could have German and Israeli citizenships (and vice versa) at the same time. The plea comes from a left-wing party! Over 33,000 Israelis have taken German citizenship since 2000.
At the same time, the forerunner in the French precedential elections pleads to undo dual citizenship. This as a way eventually to get rid of people who originate from Arab countries. This is a right-wing plea – do you see a pattern there? Le Pen: No more dual nationalities for Israelis, Americans, other non-Europeans. This is very clear to this FRENCH MP TO LE PEN: ISRAEL IS ‘LIFE INSURANCE’ FOR JEWS, WE WON’T RENOUNCE CITIZENSHIP.
Not entirely different from the reason why the Dutch do not allow dual citizenship is their dislike of incorporating too many Arabs. And no parliamentarian yet has spoken of a special love for the Jews, at least to allow for them to keep their Dutch passports next to their Israeli ones.
One person who runs in the upcoming national elections for an anti-Zionist party in The Netherlands wants dual citizenship for all nationalities with the Dutch, which would not specifically or purposely also profit Dutch with Arab roots or with Jewish roots or vice versa. It is to be seen if he can turn around enough of his future colleagues eventually. Dual nationality and the Dutch elections: candidate Eelco Keij from D66 explains.
While US and UK Jews in Israel enjoy dual citizenships, many Europeans Jews don’t. However, it seems obvious that being members of two nations can profit both states.
It seems that the main reason to block dual citizenship is supremacy nationalism, the dislike of and disdain for other nations compared to one’s own. Such an arrogance costs both states, but such is the nature of irrational hatred: it allows for acts that hurt every party involved.
