Simcha613:
There are practical implications to understanding that the State was and is assur to have been founded.
For example, when those misguided Jews realize that this State was indisputably founded in severe sin, they are less likely to continue doing as Rav Elchonon wrote and as Rabbi JB Soloveichik quoted from his father, which is to fuse the A”Z of Zionism with, lihavdil, their Judaism.
Instead, they will, presumably, revert to their pre-Zionist unadulterated Judaism as do the portion of Jewry who have B”H seen past the lies of Zionism.
