[Avodah] Building settlement by non-Jewish workers permitted on Shabbat

[Moshe Feldman]

"It has now become clear," [Yated Ne'eman] continued, "that one sin
leads to another... and some of them [the religious-Zionists] have now
decided that the settlements must be built even on the holy Sabbath...
This grave phenomenon reminds us once again that the 'nationalist
religion' continues to break down barriers amidst a distorted scale of
values according to which, nationalist and Zionist values take
precedence over the entire Torah."

Rav Gisser responded:
<< It is written in the Talmud five times, and many times in Jewish
Law, that asking a non-Jew [as above] for the purpose of acquiring a
house in the Land of Israel on the Sabbath is permitted."
>>

I don't have access to the article in Yated Neeman (it's not Deah
v'Dibbur website).  Anyone know what the argument is to forbid
non-Jewish workers from building in Eretz Yisrael on Shabbat?  Unless
they hold that the settlements will probably be given to the Arabs
anyway, and therefore this does not give us a foothold in EY?
