> just saying Israel lobby pushed SCOTUS to legalize Roundup because they are using it for chem warfare in Lebanon

This court decision wasn't about legalizing Roundup. Roundup was already 100% legal before this court decision, so there is zero reason for anyone to have pushed this court to legalize it. Even if the US suddenly decided to make Roundup illegal to use, in what way would that prevent Israel (or any other country outside of the US) from using it? Not only is what you are saying factually wrong, it wouldn't make any sense even if it were true.
