As Rabbi Ribner pointed out recently in one of his podcasts, the Briskers are very big into tziyoinistim yemach shemam vezichrom. HOWEVER, they don’t hold of the 3 Oaths as a thing. As well, Chazal say (Sanhedrin 64a, Yoma 69b) that the taava for avoda zara was battul. So if you take the Satmar Rebbe literally that Zionism is avoda zara, you are forced to say he’s arguing against befeirushe gemaras that there is no taava for avoda zara anymore. You are forced to say that he meant it as a melitza bealma so as not to have him being soseir the gamaras.
Not a Zionist, not a Satmar, just trying to add some honesty in this debate.
