Do some nations hate Jews

Answer 1

Yes. There should be two ways for a nation to be considered a "Jew-hating nation", (1) nations where 75% of more of the general population harbor Anti-Semitic views, or (2) nations where the government actively condones or supports Anti-Semitism or espouses strongly Anti-Semitic views. Countries of both types exist.

(1) Anti-Semitic Populations: According to the ADL Global 100 survey, the following 16 countries had populations where at least 75% harbored Anti-Semitic Views: Palestine, Iraq, Yemen, Algeria, Libya, Tunisia, Kuwait, Bahrain, Jordan, Morocco, Qatar, United Arab Emirates, Lebanon, Oman, and Egypt. Additionally, the survey did not include the following 6 countries which would likely also have populations where at least 75% harbor Anti-Semitic views: Syria, Afghanistan, Pakistan, Mauritania, Sudan, and Somalia. It is worth noting that we see no similar characteristics or surveys concerning the prevalence of hatred towards other ethnic or religious groups with the singular exception of the Romani/Gypsies.

Also note that this survey and other similar surveys ask questions about Anti-Semitism only and do not ask questions that could be construed as Anti-Zionist, but not necessarily Anti-Semitic. Particularly Anti-Semitic views include, among others: (1) that Jews exert an strong amount of control or direction on politics and economics, (2) that Jews murder Non-Jews in order to gain access to their blood - usually for ritualistic purposes, (3) that Jews are disloyal/treacherous/deceiving to Non-Jews, (4) Holocaust denialism or "revisionism", and (5) that Jews provoke or cause most of the world's wars.

(2) Anti-Semitic Governments: There are several countries whose governments have actively fanned the flames of the Anti-Semitism and have espoused Anti-Semitic doctrines as part of government policy. The most prominent today is Saudi Arabia, which has a number of Anti-Semitic laws and policies such as: (1) making it virtually impossible for a Jewish tourist to come to Saudi Arabia, (2) legally banning Jews from living or working in Saudi Arabia, (3) confiscating any Jewish religious paraphernalia, (4) paying for the printing and disseminating Jewish-hate literature such as the Protocols of the Elders of Zion and Mein Kampf (although, surprisingly the Arabic version Kefaahi - كفاحي leaves out Hitler's half-chapter where he explains that Arabs are sub-humans that he respects because he sees Islam as a violent, conquering ideology that he feels like Germans should emulate), (5) funding mosques and imams in other countries to promote a Wahhabist agenda which includes, among other things, promoting Anti-Semitism.

Another Anti-Semitic government is that of the Islamic Republic of Iran, which actually hosted a Holocaust Denial Conference. While there is debate about whether the number of Jews who were killed is 5.4 million up to 7.5 million, there is no legitimate debate that at least 5.4 million were killed, and the conference sought to minimize the number by orders of magnitude, i.e. 100,000 or so, or deny it completely. Iran has also provided direct funding to Hezbollah, whose founder Hassan Nasrallah is famously quoted as having said that he would prefer that all of the Jews came to Israel so that he would not have to hunt them down all over the world.

Another Anti-Semitic leader is the former Prime Minister of Malaysia, Mahathir Mohamad of Malaysia who argued at the Organization of the Islamic Conference that Jews "cunningly get others to die on their behalf" and defended this statement against righteous international scrutiny.

Note again, that, with the exception of the Romani/Gypsies and possibly the Baha'i in Iran, no ethnic or religious group is targeted by various different governments in such a systematic way.
