I don’t know the source for this, but I hear the Gra said the warning of Kesubos 111a of “Choma” refers to building the Holy Temple, not mass immigration to Israel at all! So says Wikipedia.
A reminder:
שלושה שבועות הללו למה אחת שלא יעלו ישראל בחומה ואחת שהשביע הקדוש ברוך הוא את ישראל שלא ימרדו באומות העולם ואחת שהשביע הקדוש ברוך הוא את העובדי כוכבים שלא ישתעבדו בהן בישראל יותר מדאי
Whether these oaths are still binding is a separate matter. No oaths, but I hope to investigate this further on this site.
And this strengthens my case that Rabbi Yoel erred in his opus by not attacking the positive commandment of rebuilding the Holy Temple. If you want to destroy Judaism, undermining the Jewish tongue, Jewish sovereignty, and the Jewish land are a good start, yet insufficient. He should have realized: the next frontier will be the Jewish Temple, and he will have had no credit in trying to prevent it. But of course, Rabbi Yoel was anything but prescient.
(On second thought, see this.)
