I fully understand the desire for an Israel minyan, and I certainly understand this Rav’s psak, as it is in tune with the general drift of the last thirty years. But I think it is a very wrong psak.
The parsha this week in America is Nasso. Period. Any other kriah, a communal obligation, is the wrong kriah. Period. To lein the following parsha with a minyan is leining the wrong parsha.
The same applies when Americans come to Israel for yomtov and make minyanim as if they were in America. They are reading the wrong kriah and davening the wrong tefilah, this is Israel and not America. Furthermore, it is a slap in the face to the people of Israel when this is done. The Rav of Yerushalayim, the saintly Rav Shmuel Salant zt”l was vehemently opposed to this practice. Unfortunately, the tides have changed, and now one can come to Yerushalyim on yomtov and think he is in Flatbush. I think it is wrong, but that is the reality.
So, I oppose looking for this Israel minyan, but I am in the minority, and I hope that you find one.
