Why has Israel become a world power so quickly? (Remember that the Second World War ended in 1945 and it was only the following year that the state of Israel was created) ps: I picked the subject history for this question but the question is actually from religion

Jackson pollock described his art style in the following quote: “new needs need new techniques.… it seems to me that the modern painter cannot express this age, the airplane, the atom bomb, the radio, in the old forms of the renaissance or of any other past culture. each age finds its own technique.” what point is pollock making about the new styles of art?
