176. With regard to the principle of self-determination, although international recognition was extended to this principle at the end of the First World War and it was adhered to with regard to the other Arab territories, at the time of the creation of the "A" Mandates, it was not applied to Palestine, obviously because of the intention to make possible the creation of the Jewish National Home there. Actually, it may well be said that the Jewish National Home and the sui generis Mandate for Palestine run counter to that principle
Well, actually, from your link:
(1) The placing of the country "under such political, administrative arid economic conditions as will secure the establishment of the Jewish National Home, as laid down in the preamble . . ." (article 2) considered together with the obligation to "facilitate Jewish immigration under suitable conditions" arid "encourage, in cooperation with the Jewish Agency referred to in article 4, close settlement by Jews on the land, including State lands and waste lands not required for public purposes" (article 6).
So, as we see, the Mandate provided for establishment of the Jewish National Home and immigration of the Jewish people was intended to facilitate that.
In your Jew-hating universe, you just can't accept the intent and facilitation of Jews reclaiming their ancestral homeland after the Islamist Entity™ had all but purged existence of the Jewish heritage from muhammudan'istan.
