Ignorance and War (for Christian pacifists)

I wonder if one could argue that ignorance can be a cause of war. I know a few christians (among them also some catholic priests and even a couple of bishops) that like to talk about peace but do not like to study theology or philosophy. If you do not study you could become prey to ignorance which in turn, as everybody should know, is a breeding field for prejudice and wrong assumptions (all of which undermine truth). If, then, it is true that TRUTH is a pillar for builduing peace, with a simple syllogism we could come to the conclusion that those who dislike study are not really working towards building peace, but the reverse.
It is said that a big factor that led to the genocide that happened in Rwanda,was mutual (and carefully protected) ignorance between Tutsis nad Hutus.

無知と戦争

無知は戦争の原因になるということを主張できないであろうか。私は平和について話したがるクリスチャン（そのうち神父数人、司教若干名）を知っている。けれども、彼らが哲学や神学を勉強したがらない、むしろどちらかといえば嫌いなんです。勉強しなければ当然無知になる。無知は、周知のとおり偏見と先入観の温床ではないか。偏見と先入観は真理をむしばむもの。だとすると、歴代の教皇が強調するように、真理は平和の柱であることはほんとうであれば、簡単な算段論法で帰結できることであるが、勉強嫌いな人は平和を築くのではなく、むしろ逆である。
