Zechariah talks about a time when "all the nations of the earth" will come together and try to invade Israel.
.......................After this invasion, Zechariah's prophecy, describes a supernatural judgment that will come on all the nations who took part in the invasion.
.................These nations are destroyed through earthquakes, giant hailstones and tornadoes.
If they invade Israel and send in forces to keep peace, Bible scholars believe that this would be a fulfillment of this prophecy.
