My impression is that these three religions are pretty out of mainstream of World's religions. Their only strength is more militant aggression. In particular, "religious wars" is probably not a normalcy at all in wider history. Yes, people were fighting wars, but not particularly to mess with each other's beliefs. Or even stronger: a general religion is not so much about beliefs, but spiritual-practical way of life. (I am not original with this, in fact.)

If Islam and Judaism are more similar to each other than to Christianity, the most logical question is: why is Islam and Judaism not together?! Perhaps belief purity is more a political tool than a genuine human need, after all. Christianity's "choice" obviously benefits its broadly dominant status.
