DY, I am. However, in general Jews should make aliya. Similarly, Jews should keep other mitzvot. Others should not.
ZD, I hate to burst your bubble but Rav Shteinamn is not the only gadol. Rav Ovadia and Rav Mordechai Eliahu supported aliya and Rav Avtaham Shapira, when speaking in the US, looked out and asked “What are you doing here?”
Besides, the statement was related by Rabbi Yitzhak Katz in the name of his talmidim who asked Rav Shteinman. In other words, third hand info. On that, Rav Scheinberg, when told that he had been misquoted, said “If I had nickel for every time I was misquoted I would be a rich man”. Once an avereich who was writing a sefer on hilchot tefillin asked Rav Elaishiv a question regarding chatzitza. When RE said that it was no problem the avereich argued with him until finally he said “If you think it’s assur then let it be assur for you”. The avereich wrote “RE said that it is good to be machmir”. Once some people advertised a tiul to Chutz laARetz “withthe advice of Rav Mordechai Eliahu”. Rav Aviner asked RME who said “They asked. I said it’s assur. So they wrote that I advised them”.
