HaKatan, we have discussed the Three oaths before but i am willing to repeat it 400 times if necessary.
1. They are not found in any of the Codes. Not in Ramabm, bot in the Tur and not in the Shulchan Aruch.Rav Asher Weiss says that something lie that is NOT halacha pesuka.
2. Rav Chaim Vital (introduction to “Etz HaChaim” says that they were only for 1,000 years.
3. The gentiles violated their part of the bargain repeatedly (Crusades, expulsions., Chmielnitzky massacres, Holocaust).See Sota 9b-10a and Rashi10a d’h huchal shevuato shel Avimelech)that this nullifies the whole deal
4. The Ohr Sameach wrote in a letter to the JNF (to which he contributed from his own pocket) that if they ever existed the San Remo Conference repealed them.
5. Rav Soloveichik says in “Kol Dodi Dofek” that the Hashem has called and nullified them.
6. Rav Kahneman flew the Israeli flag at Ponevich every Yom HaAtzmaut so obviously he did not hold like you.
BTW, being that we are discussing Ponevich, Rav Edelstein says that one who does not vote in the Israeli elections is a poresh m’darchei tzibbur.
