after the State of Israel happened, people stopped opposing it since its existence must have been from Hashem.
A similar Shittah was held by many others, that once the State is in existence then protesting it would give support and comfort to Sonei Yisroel (as we have seen happen). Agudah in EY took a different approach, in which they don’t support the state, but don’t specifically go against it (for the time being) and get support (money) from the state.
DY once showed me a fascinating written version of the Agudah Shittah post ’48 from one of the Gedolim, perhaps he could find it and copy it here as well?
