From two components this identity originates:

You cannot extract one without damaging the other;

Either–or doesn't apply here.

Inclusiveness is the key—

We are Russians and Jews,

Both are conjoined in us,

All mixed together and inseparable …

Yitshak was sitting on a park-bench and was staring without blinking at that country road, running not on earth but through the sky. Through the efforts of a weakening brain, similar to an old radio with exhausted batteries, he was tuning in to some long-gone waveband, attempting to give it its old resonance and clarity. He brought out of oblivion bleeding chunks of life in the hope of putting them together into something living, or, if not wholly alive, then at least pulsating, trembling, not yet moribund.

all those who, when asked, identify themselves as Jews; or, if the respondent is a different person in the same household, are identified by him/her as Jews … Such a definition of a person as a Jew, reflecting subjective feelings, broadly overlaps but does not necessarily coincide with halakha (rabbinic law) or other normatively binding definitions. Inclusion does not depend on any measure of that person's Jewish commitment or behavior in terms or religiosity, beliefs, knowledge, communal affiliation or otherwise.
