Up till now, Hebrew is the main language spoken in Eretz Yisrael. But if leftist continue in power, soon it'll be Arabic.
And there is a little difference in the Hebrew spoken by Torah Jews, and that of the Leftists. Just some examples.
Shalom (Peace). /Leftists' Hebrew (Allow Arabs to kill us)
Mechabel (Terrorist) /Leftists' Hebrew (Nobel Prize)
Har Habayt (Temple Mount) /Leftist's Hebrew (Holy Muslim site forbidden to Jews)
Yahadut (Judaism) /Leftists' Hebrew (extremism)
