Observance of mitzvot are important, but they are the result of being AUTHENTICALLY Jewish. There's an old yiddish expression which, roughly translated, states, "first of all, be a human being." The yiddish word for human being is "mensch" with all its connotations of substance over form. When an Arab murders four young girls and then shoots their pregnant mother in the belly, the AUTHENTIC Jews cries out in pain, and demands justice. Those who are merely born to Jewish parents react by giving up land to murderers.
Speaking for myself, justice would be dropping a kosher, 50 megaton, bagel-shaped bomb on Mecca.
