As a Jewish American, I don't think it's antisemitic. We really shouldn't be sending any money or weapons to Israel or joining them in any wars.
What I do think is a bit antisemitic is the suggestion that Israel is somehow unique here. Russia, China, and the U.S. are all doing this. Heck we just captured Maduro and killed leader of Iran. I just think a country like Russia is way more effective and subtle when it comes to election manipulation, especially in Eastern Europe.
So, if I don't follow your what-about-ism, Im a racist? Thats what you are saying there; We all know that the US, china, Russia, and 99% of the countries in the world are doing this. Why is it racist to pick on the COUNTRY of Israel, which right now is trying its hardest to wipe out entire countries? We know Russia is doing that right now in Ukraine, but that does not eliminate what Israel is doing.
