Mythbusters - Sterilization of Ethiopian Jews

To my knowledge the states that allow "at least one grandparent" right of return are miniscule , and either way that doesn't prove the rightness of such law.

Greeks born abroad transmit citizenship to their descendants indefinitely. It is way more than "at least one grandparent".

Some of the minuscule European countries that naturalise people with at least one grandparent are Italy, Ireland, Germany, Greece, Armenia, Bulgaria, Romania, Croatia, Finland, Hungary, Slovakia, Czech Republic, Serbia, Turkey, Estonia, Russia. You are eligible to apply for Spanish citizenship if one of your parents, grandparents or great-grandparents was Spanish. The UK grants Ancestry visa to those who can prove at least one grandparent was British and then a clear path to citizenship.

Sovereign states have the right to determine their own immigration policy and your views on the matter are irrelevant.

Israel does not grant right of return based on a 2000-year old claim. Israel grants right of return based on its immigration laws.

Immigration is very off topic to the thread. You could make a thread about jus sanguis or research it yourself.
