Fait Accompli example: A couple gets married against our advise and have children. Afterwards we will pray for their happiness and success.
BS”D
A Jew goes off the path and marries a non-Jewish woman despite all of our efforts to stop the intermarriage.
We daven day and night and do whatever we can so that either the non-Jewish partner becomes a ger tzedek and the children convert (the equivalent of the medine electing, if not a frum government, at least a government that is proudly Jewish and will uphold Jewish values, defend our mekoimois kedoishim, and cease to cause anti-Semitism throughout the world by its incompetent actions and lack of ability to either wage a decisive war or make a decisive peace).
Alternately, we do what we can so that the marriage breaks up (in this case we daven for the peaceful dissolution of the medine so that, as Aguda really wanted, Jews would have rights to have Torah communities, access to mekoimois hakedoishim, but no sovereignty). We tell the non-Jewish partner that she is not ours and we will not tolerate the way she has corrupted a pure Jew (the medine vs the Jewish people) but we cannot kill the non-Jewish partner or cause her any harm.
Since neither in the case of the hypothetical marriage nor in the case of the medine will this happen al pi teva, we daven for Moshiach to come and replace the memsheles zadoin with Malchus Beis Dovid, all the while trying to ensure, by whatever means necessary including dealing with and in a way subverting the corrupt structures of the medine (Aguda of today, Chabad), that no further physical or spiritual damage is caused by the medine.
This present state has NO sanhedrin and no kedusha. Those who serve in its army do indeed protect their fellow Jews, but the reason the army has not been wiped out is ONLY because of the Torah life which goes on in E”Y DESPITE the best efforts of the medine. The failures of 1973 and Lebanon and the recent cowardly surrender in Aza should make that clear by now.
