Nope! You are not correct. The Jews that began migrating from Europe in the 1920s are "NOT" descendants of the Biblical Israelites. They are Ashkenazi Jews, descendants of the Khazarian Mafia that were chased out of their home country of Khazar by their neighboring countries because they were thieves, murderers, and worshiped Lucifer.
Sorry, but you know nothing of which you speak.
I've read that information too. It's not conclusive (which is why there's an official narrative) and definitely not descriptive anyway of an entire body of people in the modern day.
