The Satmar Rebbe zt”l certainly didn’t hold of everything in the Divrei Yoel, since he tried twice to settle in Eretz Yisroel and allowed municipal voting in 1955.
The Satmar Rebbe zt”l was one of many gedolim in that tekufa. there was no bas kol declaring him more authoritative than the other gedolim at that time. Certainly other gedolim can argue on him.
