Why muslim countries are not united against Israel? What is going on is not a real war, is just retarded. They keep firing missiles at Israel randomly, then Israel responds with seriously destroying everything. Why Muslim countries can't just unite and erase Israel in 24 hours with all their weapons?
This shit is all retarded fake.
After the great schism the 2 churches despised each other. Centuries of disputes ranging from name-calling to outright war and mass murder followed. The Greeks killed 60,000 Catholics in the 1100s just cause. The venetians sacked Constantinople. At many points both sides acrively preferred Muslims to each other.
This continued even into the 1800s with the crimean war basically being France's "fuck you" to the orthodox church because reasons.
I think this mirrors the sunni Shia schism. But the great schism was probably even more violent overall.
It's simple. The great schism is such a clusterfuck that there's still inquiry into how the hell this happened 1000 years later. Chief reason given is the filioque. That is far from the only reason, just the straw that broke the camels back. There are dozens if not hundreds of reasons why the great schism happened.
It can be summed up as follows:
Islam schism: succession issues
Great schism: 1000 years of slight theological differences between eastern and western catholicism snowballing into creating 2 completely different sects
Reformation: the western catholic church pissed a bunch of people off
