The only organisation that unites man from every part of the world regardless their race or country is the Catholic Church.
The only wars during those periods where the Catholic Church was strong were:
>Between Christian countries, but for political reasons not religious
>the Crusades. Muslims were destroying our homelands and converting people to Satan. And souls being lost are very real so self defense was needed.
<muh Spaniards killed the natives
Not their fault they carried lethal bacteria they weren't immune to. Every other killing was due to the same reason the brits and the Americans killed the natives in the USA, that is not about religion.
Either way south America proves we were nice to them since most of them are Catholic and half breeds.
Now when the catholic Church lost its power on the states, 19th and 20th centuries, just the WW2 killed more people than all the wars together before.
And now wars are waged about everything, it doesn't matter the ones killed are innocent as long as the country has oil or Israel says they're bad.
