The fighting throughout history between the Jews and Christians was much worse than it is now. What fighting, specifically, are you talking about now? What is it exactly that you like like to see happen? I'm not sure I completely understand what you're hoping for? Also, which fight exactly are you talking about that occurred 2008 years ago? Christians have fought with many people, not just Jews and this has happened throughout history. Jews have been discriminated against by many different groups as well, some Christian and some not.
But, as of right now, I can't say I see very much fighting going on specifically between Jews and Christians. I'd say the bigger problem would be Muslims fighting everyone, at this point in history. Unless you want to bring up the Holocaust, in which I'm not sure you could say that was Christians fighting Jews, but rather Germans killing Jews, and the world doing nothing.
