No, modern leftism was born in France in the 18th century with the French Revolution, whose leaders were not jewish. Jews have hated all non-jews as long as they have lived. They did not gain power until leftism gradually obliterated safeguards against treason over the next 200 years. Consider Iran, where jews have lived for millennia, but have no power, because the Western left has no presence there.
If we remove jews from power and ideally from existance, leftism will disappear overnight... well, within a generation at least.
But just so happened to do everything jews ever wanted. Sure, sure.
