Israel seems like a pretty antisemetic country to me:
Any Jew who immigrates to Israel as an oleh (Jewish immigrant) under the Law of Return automatically becomes an Israeli citizen. In this context, a Jew means a person born to a Jewish mother, or someone who has converted to Judaism and does not adhere to another religion. This right to citizenship extends to any children or grandchildren of a Jew, as well as the spouse of a Jew, or the spouse of a child or grandchild of a Jew. A Jew who voluntarily converts to another religion forfeits their right to claim citizenship under this provision.
Foreigners may naturalize as Israeli citizens after residing in Israel for at least three of the previous five years while holding permanent residency. Candidates must be physically present in the country at the time of application, be able to demonstrate knowledge of the Hebrew language, have the intention of permanently settling in Israel, and renounce any foreign nationalities. Although Arabic was previously an official language and has a special recognized status, there is no similar knowledge stipulation for it as part of the naturalization process. All of these requirements may be partially or completely waived for a candidate if they: served in the Israel Defense Forces or suffered the loss of a child during their military service period, are a minor child of a naturalized parent or Israeli resident, or made extraordinary contributions to Israel. Successful applicants are required to swear an oath of allegiance to the State of Israel.
Dual/multiple citizenship is explicitly allowed for an oleh who becomes Israeli by right of return. This is to encourage the overseas Jewish diaspora to migrate to Israel without forcing them to lose their previous national statuses. By contrast, naturalization candidates are required to renounce their original nationalities to obtain citizenship. Persons opting to naturalize are typically individuals who migrate to Israel for employment or family reasons, or are permanent residents of East Jerusalem and the Golan Heights.
Male spouses under 35 and female spouses under 25 ordinarily resident in the Judea and Samaria Area (administrative division for the West Bank under Israeli law) outside of Israeli settlements are prohibited from obtaining citizenship and residency until reaching the relevant age. The 2003 Citizenship and Entry into Israel Law effectively discouraged further marriages between Israeli citizens and Palestinians by adding cumbersome administrative barriers that made legal cohabitation prohibitively difficult for affected couples. About 12,700 Palestinians married to Israeli citizens are prevented from obtaining citizenship under these restrictions. Affected persons are only allowed to remain in Israel on temporary permits, which would lapse on the death of their spouses or if they were to fail to receive regular reapproval by the Israeli government.
