In the Torah (Jewish Holy book), God ordered the Jews to completely exterminate all men, women, and children of the Amalek. Why? Because they opposed the Jews in carrying out God's mission for them to "fix the world".

Rabbi Elyahu Kin from the Torah Ohr Synagogue in Los Angeles teaches his congregation that God's command to Jews to commit genocide still stands. And today, Amalek means all nations that oppose the Jews efforts to "fix" them. This includes America and most of Europe.

Some highlights:

1:51 Why does this commandment appear to be so cruel? After all it asks us to Exterminate! To kill Men, Women, and Children

18:40 the torah will be given and it will provide a blueprint, a guide, a map to the Jewish people, a nation, to tell them what to do, how to rectify this world - Fix it! - clean it up!

27:42 the Jews have this job, to fix this world, to rectify this world, to bring about HaShem's (God's) dwelling in this world.

28:55 We can not allow him (Amalek) to exits. He (Amalek) is the one who is interfering with our job

40:00 Why be so cruel to him? Get rid of all of him? Men, women and children? Some people accuse us of being those who believe in genocide. That's what this is calling for right? Being so cruel, sadistic.

42:49 We are cruel to Amalek because we need to be. Because that is exactly what they would do to us if they had the chance. ... If we do not do it to him he will do it to us. So is that being cruel to him or is it being self-defense? The Torah tells us you gotta do it because he's gonna go it to you.

44:40 This is the concentration of evil. The greatest evil. The Archenemy of the Jew. What difference does it make if it's a baby? Or if it's an adult. It's the same thing, this baby will eventually be an adult. And this baby will eventually try to harm you. Do it to him before he does it to you. And you better do it because he is your enemy. ...

52:12 There are people who will always look back and say "let's just make peace with them. Let's befriend them. They are more civilised today". Torah says no. Don't come to terms, don't let your heart be appeased and complacant with Amalek.

56:40 Okay so now we've come to the question. So who is he? Who is he today? Rabbis tell us that there will be a nation in the world, right before Messiah comes, that we will be able to tell from their character and behavior who he is. And the answer is very clear: Germany. Commentaries talk about how the concentration of Amalek is mostly in that country. Does it come as a surprise? No you can see what they did and what they are capable of doing. But there's Amalek all over the world. Amalek is everywhere.

1:02:02 - Edom is the grandfather of Amalek. If Amalek is Germany, then who is Edom? Edom includes most of Europe. It includes the United States of America.

1:03:58 - Jews received a mitzvah (command from God) of destroying any vestige of Amalek...[which includes America and most of Europe]
