Well every one gave the answer.  But there is one more thing Israel needs to do before they will gain control of their land back and until that happens it will not be.

Matthew 23 (New International Version)

  Matthew 23

37"O Jerusalem, Jerusalem, you who kill the prophets and stone those sent to you, how often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were not willing. 38Look, your house is left to you desolate. 39For I tell you, you will not see me again until you say, 'Blessed is he who comes in the name of the Lord.'[d]"

I realize that many Jewish people believe in Jesus.  But, as a nation  they have to cry out to him, and according to what I understand that will not be until they are surrounded by all sides by their enemies.

Luke 21 (New King James Version)

  Luke 21 The Destruction of Jerusalem
   
20 “But when you see Jerusalem surrounded by armies, then know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her. 22 For these are the days of vengeance, that all things which are written may be fulfilled. 23 But woe to those who are pregnant and to those who are nursing babies in those days! For there will be great distress in the land and wrath upon this people. 24 And they will fall by the edge of the sword, and be led away captive into all nations. And Jerusalem will be trampled by Gentiles until the times of the Gentiles are fulfilled.

My heart goes out to you people.  You are God's chosen people and are the center of the Earth.  God's wrath has been on you since your ancestors crucified Jesus.
No one has all the answers only the Lord does. 
I have never been to Israel, but I love it because our dear Savior was born in the flesh there.  So Israel you tug at my heart because I know the love our dear Savior has for you.  I love him, so therefore, I love you.
