I suspect Jews and Christians aren't really worshiping the same God. The Christian God is clearly a universalist conception above culture, while Yahweh sounds like just another tribal god conveniently focused entirely on the culture that invented him.
Vox Day makes a good point that "Judeo-Christianity" is just a tool for Jews to ingratiate themselves to Christians and get what they want out of them. Notice how the cooperation between Jews and Israel-supporting Christians is one-way: Christians that think Israel needs to exist for Jesus to come back support the Jews while Jews still take every opportunity to shit on Christians.
