It is entirely based around religion.
Israel believes it is "entitled" to the land because it was given to them by "God" as per the Bible.
Let's start with Nazism shall we? That was a war based around religion
On one side the Nazi's were engaged in antisemitism to wipe out the Jewish religion.
The Nazi's also leveraged religion in order to undermine Judaism.. Hitler was also propped up as a "New Messiah".Religion was a very big part of that war.https://en.wikipedia.org/wiki/Nazism#Religion
Communism is an economical doctrine... And one could argue full communism hasn't been achieved by any country yet, not even China which has Capitalistic aspects underpinning it's market based economy.
...and some of the world's greatest humanitarian efforts have been carried out by religious organizations, e.g. the Catholic church being the world's largest non-governmental provider of education and medical services
the world needs to get rid of extremism
Yes the Catholic Church gives allot, no one denies that.
They essentially have a "Store" in every single town/city/suburb, in every single state, in almost every single country on Earth... And you have people donating regularly... In return they offer various services that aids in indoctrination to keep the donation cycle going, it's a a lucrative business.
But Religion isn't a requirement to help others. - I'm not religious, neither is anyone in my Brigade, my job revolves around saving lives daily.
The Catholic Church can help so many people because they have a large revenue stream from it's paying customers, Governments also give them a free pass on things like Tax (Which I think Church's should pay for) so they have the resources to do it... And often Governments will "Donate" hoards of cash to assist various populations.
But don't kid yourself, there is some abuse that goes on in the Church
. - They will often spend up big on campaigns (I.E. Same Sex Marriage) in order to try and turn voters to their agenda, they are very much entwined in American Politics... Heck even Australian politics but to a far lesser degree thankfully.
For example during last years catastrophic bushfire season here, Australians handed over hundreds of millions of dollars to various organisations, many of which were religious in order to assist us Firefighters with basic needs like Food and Sanitation... But also to assist those who needed to rebuild/recover from the fires as well.
Instead the religious organizations "Held back" (And continue to hold) hundreds of millions of dollars arguing "They will spend it later". - As you can imagine, it did result in a shit storm and deservedly so.
There are also plenty of non-religious organizations which help more than any singular church... The United Nations supported World Food Program is one such example and is the largest humanitarian program in existence.
You also have the Bill and Melinda Gates foundation as well.Point is, religion isn't the requirement to help others, nor is it a requirement in humanitarian efforts either.
