During the time before there was a State of Israel, those ideals in our hearts which we tried to practice and which we wanted others to practice, seemed not achievable where we were because, we felt we had no influence over our world where we were. And so, the longing for our homeland was tied into the longing for our dreams and our vision. Now that the state of Israel is with us, our dreams and our visions still remain distant from our lives and therefore when we say the Tisha B’av prayers we need to remind ourselves of the distance between that which we would have in this world and that which we do have.
