Kikes were already well off and "kike-ing" it long before they managed to convince some of the ruling elite of the khazars to convert to Judaism. Most of the standard population practiced tengrism, Islam, or Christianity. There is debate about whether the elite actually even converted to Judaism at all.
The khazars did not spread out very far, the descendants of the khazars are other central Asian turkic groups, they make up a tiny fragment of jewish dna and this is mostly by proxy of jews mixing wherever they go.
The Tamga used by the khazars was also older than their "conversion" and has cognates with turkic tribes which were never jewish to begin with. I've seen this brought up because of Ukraine's trident, and this information is patently wrong. The trident has nothing to do with judaism, or moloch. Is it related to the khazars? Absolutely, it's because Volodymyr the Great took the symbol from them, and the symbol itself is turkic, not jewish. I highly doubt a Christian Saint would take a jewish symbol.
I bring this up because narrowing down jews to khazarians is ignoring the issue and putting forth a strawman argument that doesn't have much basis, and I see it a lot. In reality, the jews were your enemy long before some khazars might have converted and they were also already finding ways to worm their way into the west long before the khazars might have converted as well.
The possible tiny minority of khazars who converted to judaism didn't go anywhere and they were conquered. Where the fuck do you expect them to go? There aren't any records of Mongolians randomly appearing in Europe in positions of high finance. No, the jews were already here. They're not khazars, they're an eldritch abomination of races.
The jews are not converted khazars. They're israelites mixed with canaanites (which already made their blood unclean), mixed with other Semitic races, mixed with Europeans, mixed with niggers, and some are mixed with turkics. This all happened before the khazars even popped into existence, and as I said, they were already coming up with a plan to infiltrate and destroy Europe before khazars existed as well.
The kike religion is the Pharisee cult and the Pharisee cult arrived the same time as the Edomite refugees. Edom was destroyed as a nation but not yet as a people. That destruction was foretold in the one chapter book of Obiadiah. Edom wanted acceptance as leaders so they went full on subversion. They claimed to have an oral Torah (first 5 books of the bible) which would become the Babylonian Talmud. The Sadducees who were the actual Israelite nobility and priesthood who had to keep their lineages called them liars and said there was no such thing as an oral torah. Kikes admit this. See table at the bottom of this page.

They also created extensive laws to make themselves appear as holy as the priesthood to the masses. This is something Jesus constantly told them off about. A modern example today would be misrepresenting not killing a cow in it's milk because it was cruel (baby cow) and making it about a fucking cheeseburger. Kikes won't eat cheeseburgers, but will fuck a kid under 3...(Ishut 3 verse 11).
Edom simply could almost pass for Romans and whites. They are from Esau, they came out red and hairy, they have always wanted their firstborn status back from Jacob (Israel).
The real Israelites were scattered to the wind. A few decades ago they used to call them the "lost tribes of Israel" because that was accepted history until kikes created pseudo history. Kikes never claimed to be from any tribe, because they never were from any tribe. Now they claim to be the Sadducee priest Levi lines that called them liars in the first place.
Khazaria was just their northern Empire that they subverted when southern countries had enough of their shit like everyone else. They were involved in the Crimean Slave trade. They HATE Slavs and view them as their property since their ancestors converted to Judaism at one time. They still view Poland and Ukraine as theirs and always will. It's why they do things like try to pressure allies into getting Poland to give them "reparations" and why they are making a big push back into those Slavic countries.
So no the kikes are not Khazars. Khazaria was just something they converted and led and a people they fucked over. That list is very long.
Kikes are the most insular, inbred people in the world which is why they have so many health problems. Sephardic, Khazaria, Asheknazi? It's all the same people. Edom. Ashkenaz is just the name for Germany's progenitor in Genesis. He was from Japeth and the 3 sons of Noah is how people were identified. Shem was SHEMite which has been changed to Semite to confuse. Japeth would be the whites. Ham was the really dark African blacks. Shem was in the middle, but Esau looked more like Japeth. It's why they can and always have shapeshifted among us.
