Here is a link to Rabbi Meir Kahane's view on the subject
I agree with Kahane-Was-Right BT that the civil war has already been started by the bad guys and we only have the choice of doing something effective to win or losing.
The blogger Maimonides stated:
When the Hebrew Tribes separated into the Kingdom of Judah and the Kingdom of Israel, it was the beginning of the end for the Hebrew nation.
My response: Why focus on that episode in Jewish history? Instead focus on the kingdom of David, which broke off first from the kingdom of the house of Shaul establishing a small Judean state with Hebron as the capital and later on the state spread to all of Israel as the house of Shaul became progressively weaker and less popular.
And don't forget what was the ultimate cause for the downfall of Shaul? The prophet said it was his undo compassion for Amalek.
A sin which is shared by many of our so-called leaders, in the state of Israel today.
Now I am willing to admit that it is possible, that eventually given enough disasters combined with the fact that the religious have larger families on average, that the State of Israel, might one day improve, even without a state of Judea. Or perhaps a huge number of religious immigrants will save us.
If someone has a better plan than the State of Judea to move the redemption forward, please inform me.
