In the US religion is absolutely being used to spearhead social conservatism and anti-government ideas. Evangelists are backing candidates who say stuff like "only while male Christians should be able to vote". And the judge appointed to the Supreme Court that shifted it to the far right has heavy ties to that same section of Christianity.

Let's not forget too that the entire reason we have this conflict is extremist Jews believe God gave them the entirety of Palestine and Syria.

Ill be honest, I am an Athiest, and I had about a year where I went through the "reddit athiest" phase where all religion is evil, but religion is very rarely, especialy in modern time (but I would argue even in pre modern) the root cause of the issue, is it a stated reason, yes, is it an accelerant to the issue maybe, but very rarely have I found it to be the rout cause.
