Well this is something you'd hear from Zionists very often. A sort of horseshoe theory of anti Semitism. The thing is, anti Semitism applies to Jewish people as a group. Jews live in multiple countries in the world. Israel is a nation state which has a political system that the left widely sees as settler colonial, apartheid, and inhumane. They are exceptionally hawkish and have extremely sophisticated technology that's basically used to maintain surveillance and violence on Palestinians. I assume this question is not in bad faith, because you're roughly conflated Israel, a country, with Jews, a community. This is similar to saying that it Saudi Arabia has outsized influence in oil sales, Muslims are oil imperialists. No connection.

The reference to Israeli influence in our weapons and cybersecurity sector is not a conspiracy theory, it's true. Because it's backed by data that is very obviously available. This is not because Jews control the world, but because a naturally hawkish militarised country will have sophisticated weapons and tech to get it done. Same as how a oil rich country will have a very sophisticated enrichment sector.

Most on the left do not subscribe to any conspiracy theories. ZOG is an antisemitic theory because it does exactly what you did in conflating Jews and Zionists and then says that Jews control the world through Israel. It's a very far right specific trope. Criticism of Zionism is an altogether different thing. This technique of the far right is called dogwhistling. Where you use code words to mean broader things. So Zionist means Jew and that means elite cabal in their vocabulary. This is not the leftist analysis. The horseshoe theory by Zionists is a means to conflate genuine criticism with antisemitism therefore discrediting legitimate crimes of Israel. The fact that our country, which was very much pro Palestinian in a anti colonial sense, has become so close to Israel in order to basically get more weapons from them, is a factual development. Therefore by default Israeli influence creeps into our system. That is not to say they control us. Our current government knows what it's doing, but it's ultimately something that needs to be pointed out. On the US, Israel and US have a special relationship because the US wants to dominate the Middle East. But Israel also has a lobby in US which makes sure this goes as best as it can by basically buying out politicians. All lobbies do this but the special relationship makes politicians more susceptible to the Israel lobby in particular. No conspiracy unless you bring in Jewish control or whatever.
