Russia's foreign minister Sergei Horseface Lavrov stepped into deep poo-poo, twice:
I could be wrong, but Hitler also had Jewish blood. Zelensky being Jewish means absolutely nothing. Wise Jewish people say that the most ardent anti-Semites are usually Jews.
After a predictable outrage from Israel, he apologized... j/k, of course he doubled down because Putinists are never wrong:
We noticed the anti-historical statements of Israeli Foreign Minister Yair Lapid, which largely explain the course of the current Israeli government to support the neo-Nazi regime in Kyiv.
At this rate, they'll start a special denazification operation in Golan Heights soon.
The irony of course is that Israel is (was?) one of the few "neutral friends" of Russia, i.e. not very keen on sanctions despite pressure from the US. I have a feeling this might change.
Lavrov is a very experienced diplomat, he is unlikely to have made a mistake. I think the Kremlin quite deliberately sacrificed a false friendship with Israel for the sake of strengthening real friendship with the Arab world in the Middle East. Israel in the current situation can do little to help Russia, and little can interfere with it - it has enough of its own problems with Palestine.
