Like Trotsky is said to be jewish just to mention some. Putin himself says USSR was mostly run by jews.
Russia/Poland/Lithuania/Ukraine have a historical love-hate relationship with Jewish people. It has a long history there, even longer than the US/Hispanic/Black love-hate relationship. You really would have to study a lot of history to understand it. I will summarize recent history for you. BTW - I identify as Jewish.
Putin is Russian, not Jewish. He thinks of Jews like a bigoted Anglo Texan thinks of Mexicans or Blacks. Not a good person to listen to on Jews or Gays.
Trotsky was a Jewish Menshevik, Lenin was a Bolshevik. Stalin took over from Lenin ... and killed most of the Jewish Bolsheviks. Lenin was part Tartar-part Russian, Stalin was full Georgian. Russians were the primary victims of the Lenin-Stalin regime. Trotsky was exiled and eventually assassinated by Stalin, for being a Jewish Menshevik. Bolsheviks were nationalists ... Mensheviks were internationalists (think R vs L communism). Stalin ruled the Soviet Union for about 25 years, and was anti-Semite. The Soviet Union continued to be anti-Semite all thru the fall of their regime, and was happy to see many Jews migrate to Israel and the US. Think of communism historically as extreme socialism.
The founders of modern Israel were mostly Jewish socialists from E Europe, prior to WW II. And a few utopians. They founded the kibbutz system (voluntary socialized agriculture). Stalin used forced socialized agriculture. Israelis dispossessed Palestinians. Stalin murdered Ukrainians (who opposed socialized agriculture). In the popular mind, in the West, from 1900 - 1970, Jewish people were associated with various forms of socialism. Both in the West, and in Israel, the socialism has been transformed into neo-Liberalism or neo-Conservativism since 1970. Jewish people have politically assimilated with their Gentile neighbors.
Part of modern anti-Semitism, is caused by xenophobic Gentiles and fear of the Rothschild family. The Rothschilds are Jewish, and the world's richest family (aside from the English royal family). They have progressively taken over banking in the last 300 years, starting with the Bank of England, and extending to the FED. They got that way by being "court Jews" .. Jews who betray Jews to Gentiles for profit. "court Jews" aren't considered good Jews. They also helped finance the founding of modern Israel. The Rothschilds cause a lot of conspiracy theories because of their power and secrecy, and are very powerful, particularly in GB and Israel. The Rothschilds may ... or may not ... be working long term for the Papacy and the European royals, particularly QEII. GB and Israel have a lot of power over the US.
The Protocols of the Elders of Zion ... is a fantasy by French anti-Semites in the 19th century, which was adopted by anti-Semites in the Russian Imperial government. It is this "original" conspiracy theory that would probably fuel Putin's views. Hitler believed in it, religiously ;-(
