I think there will always be conflicts between any group and any other group, but I think what unifies people of different faiths here are many things, but one major one is that we have a common enemy, radical Islam and even so-called (but not really) moderate Islam, either form of which wishes to destroy both the "Saturday people" and the "Sunday people". A Muslim doesn't care if you're a Jew, a Christian, a Buddhist, an Animist, or whatever. If you're not Muslim, they want to kill you.
Another major reason is that both Jews and Western Christians are generally intelligent people capable of building and maintaining a civilized and generally moral society, while many other groups of people are not.
