NO. Do Christians only speak English?
More seriously, though, most Jews speak the lingua franca or official language(s) of their country of birth or residence. For example, most American, Canadian (aside from Quebec), and British Jews speak English. Most Quebecois and French Jews speak French. Most Argentine and Mexican Jews speak Spanish. Most Russian and Ukrainian Jews speak Russian. Many also speak Jewish languages, of which Hebrew is just one of many, including: Yiddish, Ladino, Yevanic, and Judeo-Arabic.
