If there is true failure, it is only temporary. Islam will not succeed. Isaiah 19:23-25: "In that day there will be a highway from Egypt to Assyria [Iraq and Syria]. The Assyrians will go to Egypt and the Egyptians to Assyria. The Egyptians and Assyrians will worship together. 24In that day Israel will be the third, along with Egypt and Assyria, a blessing on the earth. 25The Lord Almighty will bless them, saying, 'Blessed be Egypt my people, Assyria my handiwork, and Israel my inheritance.'
