AY, many gedolim supported it.
Joseph,
a. I see that you are a baal hotzaat shem ra. In other words, you have an ownership interest in HSR.
b. The Maharal does not say that. On the contrary, he says that the oath not to make aliya en masse is connected to their oath not to persecute us “too much”. It is pure nonsense to say that they are yehareg v’al yaavor. Only the three cardinal sins are in that category (or any other mitzva that they are trying to force us to violate in order to destroy Judaism) – and that is to what he is referring.
c. I have already refuted the claims about the three oaths in this venue several times. For your benefit I will repost.
1. The pesukim cited refer to the kelei hamikdash, not the people.
2. They are aggadata. Aggadata cannot be understood literally (Rambam, Intro. to Perek Chelek). See also Responsa Chatam Sofer OC 51 at the end – and also note that the Maharshal has separate perushim on Halacha and Aggadata).
3. They are not brought down in any of the codes.
4. According to Rav Chaim Vital they were only for 1,000 years (Intro. to Sefer Etz Chaim 8).
5. According to Rav Meir Simcha the San Remo conference repealed them as the other nations agreed.
6. According to Rav Soloveichik (Kol Dodi Dofek) Hashem has called.
7. The other nations violated their oath not to persecute us too much on several occasions (Crusades, Chmielnitzky massacres, pogroms, Petlura massacres, Holocaust). Thus, the deal is off (Sotah 10a with Rashi d”h huchal shevuato shel Avimelech and Shulchan Aruch YD 236,6).
