I do not see that it was the UN who brought Israel "back into existance ". . . Rothschild capital which enabled land purchase and settler subsidies was more relevant.
But of course most here would say that G_d directed Mr. Rothschild. Correct?
Well, in order to accomplish His purposes, God led Pharaoh around by the nose, and the Ruler of all Egypt at the height of its glory was certainly many times more powerful than Mr. Rothchild.
As you go through the Bible, you see that human leaders, rulers, Emperors, etc. were all used of God to further His agenda. For example, Pontius Pilate, the most powerful man in Israel, wanted to let Jesus GO. What could be more slam-dunk certain, than an undisputed dictator having the power to let a criminal go free if he had a mind to? But God had different plans.
