Most wars have been caused by people NOT following God's wishes as documented in the Bible. There were a few special cases in the Old Testament, but generally Jesus taught his followers to "turn the other cheek" and "do not resist an evil person."
Nevertheless, he did instruct His disciples to "sell your cloak and buy a sword" for self defense against lethal force.
exactly like Jesus taught us to love one another, and the prophet Isaiah said, "shall beat their swords into plowshares" Jesus with his example also showed, he was the son of God and could have destroyed whom they were to kill but did not
then religion is the cause of wars or other interest there?
Just look at the 20th century: 20 million dead in WWII thanks to some neo-Nordic pagan lunatics in Germany, another 20 million slaughtered by the atheist Stalin, and 50 million+ thanks to the atheist Mao. The numbers killed supposedly by religion are miniscule compared to those killed in the name of anti-religionists.
hitler was supported by the Vatican, stalin asked the blessing of priests, although claiming to be atheists took refuge in religion
oh please... are you actually going to claim Hitler and Stalin were Christian or religious?
They were not Christians, but received the support of religion and most of his troops were religious.
Hitler rounded up Catholics and threw them into concentration camps.
