According to Vayoel Moshe, a sefer by the Satmarer Rebbe Zt"L, even outside of the land of Israel, the Jews prior to the moshiach shouldn't establish a state, and that regardless as to whether its character were religious or secular, that it was equally forbidden. This is due to the shalosh shavuos (3 vows) in mesechta Kesubos, one of which is not to rebel against the nations, and less pertinent to this question, one of which was not to mass immigrate to Israel.
Of course, outside of the anti-Zionist community, this sefer is controversial - but even an arch-Zionist like Rabbi Meir Kahene HY"D in his own sefer admitted these shavuous existed, and thus implied that the interpretations of it by the rishonim outlined by the Satmar Rebbe were accurate, but suggested, at length, that these vows were no longer binding ones today as his answer to why the establishment of a Jewish state doesn't conflict with the 3 shavuos outlined in that sugya.
