Are they the root, or are they a justification? Seems like a pretty reductive take, to be honest.
Wars have been occurring for a long time, and generally a desire for resources (including control over people) is a leading cause.
Religion is an easy thing to use to get people to lay their lives on the line for you if they already have that belief.
Equally it's an easy scapegoat for anti-religious people to blame wars on as well.
This conflict isn't just about religion. If it was then Israel's neighbours probably would have got involved as well.
Not really like I have seen religion actually work in making a society kind and in many places religion is the culture so without it those cultures would simply dissolve honestly I say religion is kinda like guns it can be used for good things and they both can be corrupted by bad people and used for bad things at the end of the day there are some shit people out there that want nothing but power and they see religions as a way to control people
I don't think so. The religions are an easy way to legitimate wars but they are not the first reason for them. (And look at Buddhism. They found a way to a healthy lifestyle. ~Fake News. I didn't know what happend in Myanmar and Burma for example.)
That's okay. I thought the same thing before. That Buddhism was the least of the worst because of their anti violence stance. But it turns out religion is religion.
Judaism has two meanings - religious and ethnic. (Nearly) all religious Jews belong to the Jewish ethnicity, but not all ethnic Jews are religious.
In Israel, the best indicator if someone supports the occupation in the Palestinian territories is religion. What you call Zionism ("the settler colonialist apartheid") is mainly a religious movement.
That's not to say religious Jews = bad. But a huge part of the problem is religious.
