When '..all Israel is saved...' does that mean all the biblical promised land to Israel will be restored too?

I think a lot of israelis are going to be very surprised in 5 years time. They have been educated to believe that the current state of affairs in Palestine is God's will. israelis have been duped by men. They have been sucked in, and are just grist for the mill. I think they will be shell shocked when they are asked to return to their native lands.
