Everyone in the US and Europe has been indoctrinated to support Israel for most of their lives. That’s those who support Israel and those who don’t.
If you went to literally any school, or watched any television, in the US or Europe any time in the last 7 decades, every lesson taught, every broadcast made, that could have involved Israel was pro-Israel and pro-Zionism.
Not a single program or teacher has been able to share the viewpoint that religious ethnostates should not exist, or that the native Palestinian people didn’t deserve to be genocided to make room for one. If you expressed such a view, you’d be prevented from teaching or broadcasting. For decades.
