HaLeivi:
The Arabs come into the picture for at least two two reasons:
The first is that Arabs lived in Eretz Yisrael and they did not agree to Zionist rule over them.
The second is that the Zionists fought (the Arab country) Jordan, an established government, in 1948.
As to the British “giving the land to the Jews”, the Brits themselves said that the Jews read much more into the Balfour Declaration than they had intended.
They never intended to turn over the entire “Palestine” to Zionist control, not even the part remaining after they gave away Trans-Jordan to the Hashemites.
And, in the end, the Brits never gave it to anyone but simply left the area.
The dechikas haKeitz is creating their own sovereignty in Eretz Yisrael, even if every Goy on the planet told them to, because this is something that Mashiach will do.
By the way, I don’t dispute the possibility or even likelihood that Arabs came to Eretz Yisrael because of Jewish progress in the 19th Century. But it’s not relevant to this.
The Zionists violated both oaths.
